MRI and x-ray for low back pain are surprisingly unreliable,1 because things like bulging discs usually aren’t a deal,2 most back pain goes away on its own,3 and trigger points (“muscle knots”) are common and can be alarmingly intense but aren’t dangerous.4 Most patients are much better off when they feel confident about these things. The power of justified, rational confidence is a huge factor in back pain.5 Sadly, many healthcare professionals continue to perpetuate the idea of fragile backs,6 which undermines that valuable confidence.
There are a few most common causes of hip pain. The first thing to distinguish is to identify which pain is coming from the hip, as opposed to some other source. So there are four causes of hip pain, and the pain can come from muscles, ligaments, tendons, and within the joint itself. But those types of pain present in different ways. So those are the most important distinguishing factors to find out if the hip actually is the cause of the pain.
Non-mechanical Disease Processes: Sometimes, non-mechanical disease processes like cancer, kidney stones, or a tumor may cause low back pain. These symptoms are usually, but not always, accompanied by other symptoms like unexpected weight loss, fever, or malaise that indicate a non-mechanical cause of your pain. These diseases are rare, but they can happen, so if your back pain continues for more than a few weeks after physical therapy treatment begins, a visit to your doctor is certainly in order to rule out a sinister problem.
Hip fractures, or a break in the hip bone, are another common cause of hip pain. Fractures of the hip often occur after falls in the elderly patient population. Osteoporosis puts this population at increased risk for hip fractures. Stress fractures are another form of fracture that can cause hip pain. Various risk factors increase one's risk of developing a stress fracture at the hip joint.

2016 — More editing, more! Added some better information about pain being a poor indicator, and the role of myofascial trigger points. This article has become extremely busy in the last couple months — about 4,000 readers per day, as described here — so I am really polishing it and making sure that it’s the best possible answer to people’s fears about back pain.

Activity: Bed rest should be limited. Individuals should begin stretching exercises and resume normal daily activities as soon as possible, while avoiding movements that aggravate pain. Strong evidence shows that persons who continue their activities without bed rest following onset of low back pain appeared to have better back flexibility than those who rested in bed for a week. Other studies suggest that bed rest alone may make back pain worse and can lead to secondary complications such as depression, decreased muscle tone, and blood clots in the legs.
Spartacus is worthwhile, but the sex and violence is over-the-top: there’s no sugar-coating it. Definitely not a family drama. But the dramatic quality is excellent. After a couple of campy, awkward episodes at the start, the first season quickly gets quite good: distinctive film craft, interesting writing, and solid acting from nearly the whole cast. Andy Whitfield’s Spartacus is idealistic, earnest, and easy to like. I found it downright upsetting when I learned that he had passed away — as did many, many other fans I’m sure. See my personal blog for a little bit more of a review of Spartacus. BACK TO TEXT
Bleeding in the pelvis is rare without significant trauma and is usually seen in patients who are taking blood-thinning medications, such as warfarin (Coumadin). In these patients, a rapid-onset sciatica pain can be a sign of bleeding in the back of the pelvis and abdomen that is compressing the spinal nerves as they exit to the lower extremities. Infection of the pelvis is infrequent but can be a complication of conditions such as diverticulosis, Crohn's disease, ulcerative colitis, pelvic inflammatory disease with infection of the Fallopian tubes or uterus, and even appendicitis. Pelvic infection is a serious complication of these conditions and is often associated with fever, lowering of blood pressure, and a life-threatening state.
Cycling: The repetitive movements of cycling can place a strain on your hip joints, not to mention that it can also affect your posture! If you really must cycle, make sure your bike is professionally fitted and that you properly warm up and stretch your hip flexors before getting on your bike. I’d recommend choosing an alternative though, or at least speaking to your doctor first!
Compressive pain is a result of pressure or irritation on the spinal cord, nerves that leave the spine. For example, if an intervertebral disc herniates (usually called a ruptured disc) and pushes into the spinal canal, it can cause problems with the nerve. Usually this pressure or irritation causes pain, numbness, and muscle weakness where the nerve travels.
Spinal laminectomy (also known as spinal decompression) is performed when spinal stenosis causes a narrowing of the spinal canal that causes pain, numbness, or weakness. During the procedure, the lamina or bony walls of the vertebrae, along with any bone spurs, are removed. The aim of the procedure is to open up the spinal column to remove pressure on the nerves.
But moving is important for hip and knee OA. It causes your joints to compress and release, bringing blood flow, nutrients, and oxygen into the cartilage. “This can help prolong the function and longevity of your joints,” says Eric Robertson, DPT, a physical therapist and associate professor of clinical physical therapy at the University of Southern California. 

The discs are pads that serve as "cushions" between the individual vertebral bodies. They help to minimize the impact of stress forces on the spinal column. Each disc is designed like a jelly donut with a central, softer component (nucleus pulposus) and a surrounding, firm outer ring (annulus fibrosus). The central portion of the disc is capable of rupturing (herniating as in a herniated disc) through the outer ring, causing irritation of adjacent nervous tissue and sciatica as described below. Ligaments are strong fibrous soft tissues that firmly attach bones to bones. Ligaments attach each of the vertebrae to each other and surround each of the discs.
Kneel with a wall or pillar behind you, knees hips-width apart and toes touching the wall. Arch your back to lean back while keeping your hips stacked over your knees. Take your arms overhead and touch your palms into the wall behind you. This bend does not need to be extremely deep to feel a great stretch in the hips and strength in the lower back.
The iliopsoas muscles are a group of two muscles—the psoas muscle and the iliacus muscle—located toward the front of the inner hip. The psoas muscles, in particular, is located in the lumbar (lower) region of the spine and extends through the pelvis to the femur. The iliopsoas muscles are the primary hip flexors, pulling the knee up off the ground when it contracts. Because the psoas muscle is also connected to the spine, it contributes to upright posture, assists in lumbar spine movement, and influences the spine’s curve.
If the pain is still not managed adequately, short term use of opioids such as morphine may be useful.[73][13] These medications carry a risk of addiction, may have negative interactions with other drugs, and have a greater risk of side effects, including dizziness, nausea, and constipation.[13] The effect of long term use of opioids for lower back pain is unknown.[74] Opioid treatment for chronic low back pain increases the risk for lifetime illicit drug use.[75] Specialist groups advise against general long-term use of opioids for chronic low back pain.[13][76] As of 2016, the CDC has released a guideline for prescribed opioid use in the management of chronic pain.[77] It states that opioid use is not the preferred treatment when managing chronic pain due to the excessive risks involved. If prescribed, a person and their clinician should have a realistic plan to discontinue its use in the event that the risks outweigh the benefit.[77]

Medications: A wide range of medications are used to treat acute and chronic low back pain. Some are available over the counter (OTC); others require a physician’s prescription. Certain drugs, even those available OTC, may be unsafe during pregnancy, may interact with other medications, cause side effects, or lead to serious adverse effects such as liver damage or gastrointestinal ulcers and bleeding. Consultation with a health care provider is advised before use. The following are the main types of medications used for low back pain:

Located deep in the front of the hip and connecting the leg, pelvis, and abdomen, the hip flexors— surprise, surprise— flex the hip. But despite being some of the most powerful muscles in our bodies (with a clearly important role), it’s easy to neglect our poor hip flexors— often without even knowing it. It turns out just working at a desk all day (guilty!) can really weaken hip flexors since they tend to shorten up while in a seated position. This tightness disrupts good posture and is a common cause of lower back pain. Weakened hip flexors can also increase the risk of foot, ankle, and knee injuries (especially among runners) Hip muscle weakness and overuse injuries in recreational runners. Niemuth, P.E., Johnson, R.J., Myers, M.J., et al. Rocky Mountain University of Health Professions, Provo, VT. Clinical Journal of Sport Medicine, 2005 Jan; 15 (1): 14-21.. So be sure to get up, stand up every hour or so! And giving the hip flexors some extra attention is not just about injury prevention. Adding power to workouts, working toward greater flexibility, and getting speedier while running is also, as they say, all in the hips The effect of walking speed on muscle function and mechanical energetics.

The iliotibial band is a thickening of the fascia lata, the deep fascia of the thigh. Think of it as a thick long ligament like structure that connects the hip to the lower leg along the outside of the thigh.  Tightness in the iliotibial band can cause patellofemoral pain, trochanteric bursitis, and friction syndromes at the knee. This is a hip stretch I commonly prescribe to runners and people suffering from knee pain.

Avascular necrosis (also called osteonecrosis). This condition happens when blood flow to the hip bone slows and the bone tissue dies. Although it can affect other bones, avascular necrosis most often happens in the hip. It can be caused by a hip fracture or dislocation, or from the long-term use of high-dose steroids (such as prednisone), among other causes.
The hip joint is where the ball of the thigh bone (femur) joins the pelvis at a socket called the acetabulum. There is cartilage covering both the bone of the femur and the acetabulum of the pelvis in the hip joint. A joint lining tissue, called synovium, surrounds the hip joint. The synovium tissue produces fluid that lubricates the joint and provides nutrients to the cartilage of the joint. The ligaments around the hip joint attach the femur bone to the bony pelvis. There are a number of muscles and tendons that glide around the hip joint. Tiny fluid-filled sacs, called bursae, provide gliding surfaces for muscles and tendons around the hip joint. Major arteries and veins pass the front of the hip joint. The largest nerve of the body, the sciatic nerve, passes behind the hip joint.
Discectomy or microdiscectomy may be recommended to remove a disc, in cases where it has herniated and presses on a nerve root or the spinal cord, which may cause intense and enduring pain. Microdiscectomy is similar to a conventional discectomy; however, this procedure involves removing the herniated disc through a much smaller incision in the back and a more rapid recovery. Laminectomy and discectomy are frequently performed together and the combination is one of the more common ways to remove pressure on a nerve root from a herniated disc or bone spur.

Mechanical pain. By far the most common cause of lower back pain, mechanical pain (axial pain) is pain primarily from the muscles, ligaments, joints (facet joints, sacroiliac joints), or bones in and around the spine. This type of pain tends to be localized to the lower back, buttocks, and sometimes the top of the legs. It is usually influenced by loading the spine and may feel different based on motion (forward/backward/twisting), activity, standing, sitting, or resting.
If you have hip pain, you may benefit from the skilled services of a physical therapist to help determine the cause of your pain. Your PT can work with you to develop a treatment strategy to treat your hip pain or hip discomfort. Understanding why your hip is hurting can help your physical therapist and doctor prescribe the right treatment regimen for your specific condition.
If you develop a sudden onset of low back pain, a visit to your physical therapist can help you determine the correct things to do to manage your acute pain. Your physical therapist should be able to analyze your lifestyle, movements, and overall medical history to help determine the likely cause of your pain. By focusing on these mechanical causes of back pain, you can make a change that may give you relief.
How to: Stand tall, feet slightly wider than shoulder-width apart, toes pointed out at 45-degree angles (a). Keep your back straight, knees over toes and your weight in the heels of your feet (b). Engage your glutes and thighs as you lower into a deep squat until thighs parallel to the ground (or as close as you can get them) (c). Powering through your heels, push up to return to starting position (d). Repeat.

If you’re worried you’re headed toward a surgeon’s office, there might be hope. According to the Arthritis Foundation, the best way to avoid hip replacement surgery is to get active in an exercise program. In a study, people who participated in an exercise program for 12 weeks were 44 percent less likely to need joint-replacement surgery six years later than those who did not exercise.
To ease the pain and lower your odds of an injury, don’t try to do too much at once. “Start with just 10 minutes,” says Arina Garg, MD, a rheumatology fellow at The Center for Excellence for Arthritis and Rheumatology at the Louisiana University Health Sciences Center. “Every few days, increase that time by 5 to 10 minutes.” Your goal is to work up to 30 minutes of aerobic exercise, 5 days a week.
If surgery is recommended, neurosurgeons have a variety of options available to help relieve pressure on the nerve roots. If there are several nerve roots and discs causing the pain or if there is degeneration and instability in the spinal column, the neurosurgeon may opt to fuse the vertebrae together with bone grafts and stabilize the vertebrae with instrumentation, including metal plates, screws, rods and cages. A successful fusion will prevent the disc from bulging or herniating again. Following a fusion procedure, a patient may gain restored mobility in the back, including the ability to bend over. He or she will most likely experience more mobility after surgery than before. In addition, the patient may require postoperative physical therapy.

The good news is that there are plenty of good hip stretches out there that you can do to relieve discomfort, decrease tightness, and increase mobility in your hips. Since your hips are involved in so many of the movements you make (both inside and outside of the gym) stretching them is a great way to keep them feeling good and ready to work for you. Add some of the 12 hip stretches Atkins demos below to the end of your workout, or spend 10 minutes each day just doing a few of them, to improve mobility in your hips.


Sit in a chair with good lumbar support and proper position and height for the task. Keep shoulders back. Switch sitting positions often and periodically walk around the office or gently stretch muscles to relieve tension. A pillow or rolled-up towel placed behind the small of the back can provide some lumbar support. During prolonged periods of sitting, elevate feet on a low stool or a stack of books.
Electrodiagnostics are procedures that, in the setting of low back pain, are primarily used to confirm whether a person has lumbar radiculopathy. The procedures include electromyography (EMG), nerve conduction studies (NCS), and evoked potential (EP) studies. EMG assesses the electrical activity in a muscle and can detect if muscle weakness results from a problem with the nerves that control the muscles. Very fine needles are inserted in muscles to measure electrical activity transmitted from the brain or spinal cord to a particular area of the body. NCSs are often performed along with EMG to exclude conditions that can mimic radiculopathy. In NCSs, two sets of electrodes are placed on the skin over the muscles. The first set provides a mild shock to stimulate the nerve that runs to a particular muscle. The second set records the nerve’s electrical signals, and from this information nerve damage that slows conduction of the nerve signal can be detected. EP tests also involve two sets of electrodes—one set to stimulate a sensory nerve, and the other placed on the scalp to record the speed of nerve signal transmissions to the brain.
The iliopsoas muscles are a group of two muscles—the psoas muscle and the iliacus muscle—located toward the front of the inner hip. The psoas muscles, in particular, is located in the lumbar (lower) region of the spine and extends through the pelvis to the femur. The iliopsoas muscles are the primary hip flexors, pulling the knee up off the ground when it contracts. Because the psoas muscle is also connected to the spine, it contributes to upright posture, assists in lumbar spine movement, and influences the spine’s curve.
Moist heat may help relax your muscles. Put moist heat on the sore area for 10 to 15 minutes at a time before you do warm-up and stretching exercises. Moist heat includes heat patches or moist heating pads that you can buy at most drugstores, a wet washcloth or towel that has been heated in a microwave or the dryer, or a hot shower. Don’t use heat if you have swelling.
Sit on floor with knees bent and shins stacked with right leg on top. Use your hand to position right ankle on left knee. Ideally, the right knee will rest on the left thigh, but if your hips are tight, your right knee may point up toward the ceiling (overtime, as your hips become more open, your knee will lower). Keeping your hips squared to the front of the room, hinge at the hips and slowly walk hands slightly forward. If this is enough of a stretch, hold here, or fold your torso over your thighs to go deeper. Hold for at least 30 seconds, then repeat on opposite side.
Low back pain can cause a wide variety of symptoms and signs depending on the precise cause of the pain as reviewed above. Symptoms that can be associated with low back pain include numbness and/or tingling of the lower extremities, incontinence of urine or stool, inability to walk without worsening pain, lower extremity weakness, atrophy (decreased in size) of the lower extremity muscles, rash, fever, chills, weight loss, abdominal pains, burning on urination, dizziness, joint pain, and fatigue.
Physician specialties that evaluate and treat low back pain range from generalists to subspecialists.These specialties include emergency medicine physicians, general medicine, family medicine, internal medicine, gynecology, spine surgeons (orthopaedics and neurosurgery), rheumatology, pain management, and physiatry. Other health care providers for low back pain include physical therapists, chiropractors, massage therapists, psychologists, and acupuncturists.

There are cases of low back pain that have alarming causes, but it’s rare. Once in a while back pain is a warning sign of cancer, autoimmune disease, infection, or a handful of other scary culprits.7 Over the age of 55, about one in twenty cases turns out to be a fracture, and one in a hundred is more ominous.8 The further you are from 55, the better your odds.


Bursitis is inflammation of the fluid-filled sacs, called bursa, that cushion areas of pressure between joints, muscles, and tendons. Bursitis is due to overuse or repetitive actions around the joints of the body. This inflammation results in pain that is experienced during movement or pressure. Treatment involves performing stretches and strengthening exercises to help relieve pressure from the bursa.
True numbness is not just a dead/heavy feeling (which is common, and caused even by minor muscular dysfunction in the area), but a significant or complete lack of sensitivity to touch. You have true numbness when you have patches of skin where you cannot feel light touch. Such areas might still be sensitive to pressure: you could feel a poke, but as if it was through a layer of rubber. Most people have experienced true numbness at the dentist. BACK TO TEXT
Grade III (severe): A complete tear in your muscle that causes severe pain and swelling and you can't bear weight on that leg, making it difficult to walk. You've also lost more than 50 percent of your muscle function. These injuries are less common and may need surgery to repair the torn muscle. They can take several months or more to completely heal.
Imaging is indicated when there are red flags, ongoing neurological symptoms that do not resolve, or ongoing or worsening pain.[5] In particular, early use of imaging (either MRI or CT) is recommended for suspected cancer, infection, or cauda equina syndrome.[5] MRI is slightly better than CT for identifying disc disease; the two technologies are equally useful for diagnosing spinal stenosis.[5] Only a few physical diagnostic tests are helpful.[5] The straight leg raise test is almost always positive in those with disc herniation.[5] Lumbar provocative discography may be useful to identify a specific disc causing pain in those with chronic high levels of low back pain.[41] Similarly, therapeutic procedures such as nerve blocks can be used to determine a specific source of pain.[5] Some evidence supports the use of facet joint injections, transforminal epidural injections and sacroilliac injections as diagnostic tests.[5] Most other physical tests, such as evaluating for scoliosis, muscle weakness or wasting, and impaired reflexes, are of little use.[5]

In addition to strengthening the core muscles, it's also important to address any mobility problems, says Jacque Crockford, M.S., C.S.C.S., exercise physiology content manager at American Council on Exercise, which can sometimes be what's causing pain. If specific movements like twisting or bending or extending your spine feel uncomfortable, there may be mobility (flexibility) issues at play. Doing some gentle stretching (like these yoga poses) might help. (If it gets worse with those stretches, stop and see a doctor.)


At the very least, the tension and/or spasm in muscles that cross over the hip and attach onto the pelvis can contribute to imbalance, in terms of how strong and flexible each muscle group is in relation to the others. But muscle imbalance in the hips and the spine may make for pain, limitation and/or posture problems. It can also increase the healing challenge put to you by an existing injury or condition, for example, scoliosis.
Stretching the hip muscles that sit on top of the bursae, part of the lining in your hip joint, can give you some relief from bursitis pain. Kneel on the leg that's giving you the pain, holding on to something sturdy for balance. Tilt your pelvis forward, tightening your gluteus muscles (the muscles in your buttocks). Then lean away from the side of your hip that hurts, for instance to the left if you're kneeling on your right knee. You should feel a stretch from the top of your hip bone down the side of your leg to your knee, Humphrey says. Hold the stretch for 30 seconds and repeat once or twice.
Lie on your back with your knees bent and your feet flat on the floor. Tighten your buttocks and lift your hips off the floor. Tighten your abdominal muscles and lift one foot a couple of inches off the floor. Then put it down and lift the other foot a couple of inches, all while remembering to breathe. “It’s like taking alternate steps,” Pariser says. Work up to doing 30 steps at a time.
There are many causes of hip joint pain. Some hip pain is temporary, while other hip pain can be long-standing or chronic. Causes of hip pain include arthritis, inflammatory and noninflammatory arthritis, fracture, sprain, infectious arthritis (septic arthritis), avascular necrosis, Gaucher's disease, sciatica, muscle strain, iliotibial band syndrome (IT band syndrome), and hematoma.

Pain in the hip can result from a number of factors. Sometimes diseases that affect other joints in the body, such as the inflammation resulting from arthritis, can be the cause of pain in the hip. Depending upon the cause of hip pain, the pain may occur when walking, running, or engaging in activity. Trochanteric bursitis is the most common type of hip bursitis and causes pain at the point of the hip.
You're more likely to get a hip flexor injury if you've had one in the past, you don't warm up properly before engaging in athletic activity, your muscles are already tight or stiff, or your muscles are weak from being overused. If, while exercising, you try to do too much at once in too short an amount of time, you can also put yourself at risk for a hip flexor injury.
Lumbar radiculopathy: Lumbar radiculopathy is nerve irritation that is caused by damage to the discs between the vertebrae. Damage to the disc occurs because of degeneration ("wear and tear") of the outer ring of the disc, traumatic injury, or both. As a result, the central softer portion of the disc can rupture (herniate) through the outer ring of the disc and abut the spinal cord or its nerves as they exit the bony spinal column. This rupture is what causes the commonly recognized "sciatica" pain of a herniated disc that shoots from the low back and buttock down the leg. Sciatica can be preceded by a history of localized low-back aching or it can follow a "popping" sensation and be accompanied by numbness and tingling. The pain commonly increases with movements at the waist and can increase with coughing or sneezing. In more severe instances, sciatica can be accompanied by incontinence of the bladder and/or bowels. The sciatica of lumbar radiculopathy typically affects only one side of the body, such as the left side or right side, and not both. Lumbar radiculopathy is suspected based on the above symptoms. Increased radiating pain when the lower extremity is lifted supports the diagnosis. Nerve testing (EMG/electromyogramspina bifida
The main work of your hip flexors is to bring your knee toward your chest and to bend at the waist. Symptoms associated with a hip flexor strain can range from mild to severe and can impact your mobility. If you don’t rest and seek treatment, your hip flexor strain symptoms could get worse. But there are many at-home activities and remedies that can help reduce hip flexor strain symptoms.

If you are experiencing low back pain, you are not alone. An estimated 75 to 85 percent of all Americans will experience some form of back pain during their lifetime. Although low back pain can be quite debilitating and painful, in about 90 percent of all cases, pain improves without surgery. However, 50 percent of all patients who suffer from an episode of low back pain will have a recurrent episode within one year.
Low back pain is not a specific disease but rather a complaint that may be caused by a large number of underlying problems of varying levels of seriousness.[25] The majority of LBP does not have a clear cause[1] but is believed to be the result of non-serious muscle or skeletal issues such as sprains or strains.[26] Obesity, smoking, weight gain during pregnancy, stress, poor physical condition, poor posture and poor sleeping position may also contribute to low back pain.[26] A full list of possible causes includes many less common conditions.[5] Physical causes may include osteoarthritis, degeneration of the discs between the vertebrae or a spinal disc herniation, broken vertebra(e) (such as from osteoporosis) or, rarely, an infection or tumor of the spine.[27]

Paget's disease of the bone is a condition of unknown cause in which the bone formation is out of synchrony with normal bone remodeling. This condition results in abnormally weakened bone and deformity and can cause localized bone pain, though it often causes no symptoms. Paget's disease is more common in people over the age of 50. Heredity (genetic background) and certain unusual virus infections have been suggested as causes. Thickening of involved bony areas of the lumbar spine can cause the radiating lower extremity pain of sciatica.
