Low back pain has been with humans since at least the Bronze Age. The oldest known surgical treatise – the Edwin Smith Papyrus, dating to about 1500 BCE – describes a diagnostic test and treatment for a vertebral sprain. Hippocrates (c. 460 BCE – c. 370 BCE) was the first to use a term for sciatic pain and low back pain; Galen (active mid to late second century CE) described the concept in some detail. Physicians through the end of the first millennium did not attempt back surgery and recommended watchful waiting. Through the Medieval period, folk medicine practitioners provided treatments for back pain based on the belief that it was caused by spirits.[99]
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.)

Stop focusing on a specific diagnosis. Up to 85% of low back pain can be classified as "non-specific." This means that the origin of your pain cannot be localized to one specific structure or problem. While common diagnostic tests for low back pain can show the bones, discs, and joints with great detail, no test can tell the exact cause of your pain with 100% accuracy.
Lumbar herniated disc. The jelly-like center of a lumbar disc can break through the tough outer layer and irritate a nearby nerve root. The herniated portion of the disc is full of proteins that cause inflammation when they reach a nerve root, and inflammation as well as nerve compression cause nerve root pain. The disc wall is also richly supplied by nerve fibers, and a tear through the wall can cause severe pain.

If all you’ve been doing for your lower body lately is the occasional lunge, it’s time to mix up your routine. “Our bodies move in different directions, not in one direction, so it’s important to mimic that during cross-training,” Whitesides says. That’s why instead of relying on a pattern of “lunge-squat-repeat” — you might want to throw some plié squats, or leg lifts into the mix.

Pregnancy symptoms can vary from woman to woman, and not all women experience the same symptoms. When women do experience pregnancy symptoms they may include symptoms include missed menstrual period, mood changes, headaches, lower back pain, fatigue, nausea, breast tenderness, and heartburn. Signs and symptoms in late pregnancy include leg swelling and shortness of breath. Options for relief of pregnancy symptoms include exercise, diet, and other lifestyle changes.

I’m a runner and started experiencing some familiar tightness in my hip and started getting worse everyday I ran. It’s always gotten sore after running for a long extent for the last 4 years or so. I’m glad I found this page because all of these stretches helped me realize what needed to be stretched and how tight I really was! I hope this will fix my overwhelming soreness. Thank you!

The diagnosis of low back pain involves a review of the history of the illness and underlying medical conditions as well as a physical examination. It is essential that a complete story of the back pain be reviewed including injury history, aggravating and alleviating conditions, associated symptoms (fever, numbness, tingling, incontinence, etc.), as well as the duration and progression of symptoms. Aside from routine abdomen and extremity evaluations, rectal and pelvic examinations may eventually be required as well. Further tests for diagnosis of low back pain can be required including blood and urine tests, plain film X-ray tests, CAT scanning, MRI scanning, bone scanning, and tests of the nerves such as electromyograms (EMG) and nerve conduction velocities (NCV).
Back pain can suck the joy out of your days for week, months, even years. It can definitely be “serious” even when it’s not dangerous. I have worked with many truly miserable chronic low back pain patients, and of course the huge economic costs of back pain are cited practically anywhere the subject comes up. But your typical case of chronic low back pain, as nasty as it can be, has never killed anyone.
Low back pain results in large economic costs. In the United States, it is the most common type of pain in adults, responsible for a large number of missed work days, and is the most common musculoskeletal complaint seen in the emergency department.[25] In 1998, it was estimated to be responsible for $90 billion in annual health care costs, with 5% of individuals incurring most (75%) of the costs.[25] Between 1990 and 2001 there was a more than twofold increase in spinal fusion surgeries in the US, despite the fact that there were no changes to the indications for surgery or new evidence of greater usefulness.[11] Further costs occur in the form of lost income and productivity, with low back pain responsible for 40% of all missed work days in the United States.[101] Low back pain causes disability in a larger percentage of the workforce in Canada, Great Britain, the Netherlands and Sweden than in the US or Germany.[101]
Bone scans are used to detect and monitor infection, fracture, or disorders in the bone. A small amount of radioactive material is injected into the bloodstream and will collect in the bones, particularly in areas with some abnormality. Scanner-generated images can be used to identify specific areas of irregular bone metabolism or abnormal blood flow, as well as to measure levels of joint disease.

Magnetic resonance imaging (MRI) uses a magnetic force instead of radiation to create a computer-generated image. Unlike x-ray, which shows only bony structures, MRI scans also produce images of soft tissues such as muscles, ligaments, tendons, and blood vessels. An MRI may be ordered if a problem such as infection, tumor, inflammation, disc herniation or rupture, or pressure on a nerve is suspected. MRI is a noninvasive way to identify a condition requiring prompt surgical treatment. However, in most instances, unless there are “red flags” in the history or physical exam, an MRI scan is not necessary during the early phases of low back pain.


Approximately 9–12% of people (632 million) have LBP at any given point in time, and nearly 25% report having it at some point over any one-month period.[7][8] About 40% of people have LBP at some point in their lives,[7] with estimates as high as 80% among people in the developed world.[22] Difficulty most often begins between 20 and 40 years of age.[1] Men and women are equally affected.[4] Low back pain is more common among people aged between 40 and 80 years, with the overall number of individuals affected expected to increase as the population ages.[7]
Hip flexors. These hardworking muscles are crucial in foundational movements such as sitting, standing, walking and running — they act as a bridge connecting your torso to your lower body. Some muscles in this group can be notoriously weak or tight and those of you who have ever had issues with this part of your body will know the uncomfortable pain of either all too well.  There’s a lot of debate in the world of sports science over how much you should strengthen and stretch your hip flexors — we’ll explain.
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.

Sciatica is a form of radiculopathy caused by compression of the sciatic nerve, the large nerve that travels through the buttocks and extends down the back of the leg. This compression causes shock-like or burning low back pain combined with pain through the buttocks and down one leg, occasionally reaching the foot. In the most extreme cases, when the nerve is pinched between the disc and the adjacent bone, the symptoms may involve not only pain, but numbness and muscle weakness in the leg because of interrupted nerve signaling. The condition may also be caused by a tumor or cyst that presses on the sciatic nerve or its roots.


The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.

When a muscle contracts, it shortens. Take the biceps for example. Without getting too technical, the biceps are attached at the forearm and shoulder. When your biceps contract, they shorten and bring those two points closer together. When you rest, the muscle returns to its normal length, and the two points move farther away. Constantly contracting your biceps over a long period of time would cause them to get shorter, even at rest.


According to the National Institute of Neurological Disorders and Stroke, the ancient Chinese practice of acupuncture may be effective for treating moderate, chronic lower back pain. While this practice of inserting small, thin needles into the body to restore energy flow may seem daunting at first, acupuncture can stimulate the release of pain relieving chemicals in the body.

Hip labral tear. This is a rip in the ring of cartilage (called the labrum) that follows the outside rim of the socket of your hip joint. Along with cushioning your hip joint, your labrum acts like a rubber seal or gasket to help hold the ball at the top of your thighbone securely within your hip socket. Athletes and people who perform repetitive twisting movements are at higher risk of developing this problem.

An injury to a ligament is called a sprain, and an injury to muscle or tendon is called a strain. Sprains and strains may be caused by repetitive movements or a single stressful incident. Symptoms and signs include pain and swelling. Though treatment depends upon the extent and location of the injury, rest, ice, compression, and elevation are key elements of treatment.
Emerging technologies such as X-rays gave physicians new diagnostic tools, revealing the intervertebral disc as a source for back pain in some cases. In 1938, orthopedic surgeon Joseph S. Barr reported on cases of disc-related sciatica improved or cured with back surgery.[100] As a result of this work, in the 1940s, the vertebral disc model of low back pain took over,[99] dominating the literature through the 1980s, aiding further by the rise of new imaging technologies such as CT and MRI.[100] The discussion subsided as research showed disc problems to be a relatively uncommon cause of the pain. Since then, physicians have come to realize that it is unlikely that a specific cause for low back pain can be identified in many cases and question the need to find one at all as most of the time symptoms resolve within 6 to 12 weeks regardless of treatment.[99]
Congenital bone conditions: Congenital causes (existing from birth) of low back pain include scoliosis and spina bifida. Scoliosis is a sideways (lateral) curvature of the spine that can be caused when one lower extremity is shorter than the other (functional scoliosis) or because of an abnormal architecture of the spine (structural scoliosis). Children who are significantly affected by structural scoliosis may require treatment with bracing and/or surgery to the spine. Adults infrequently are treated surgically but often benefit by support bracing. Spina bifida is a birth defect in the bony vertebral arch over the spinal canal, often with absence of the spinous process. This birth defect most commonly affects the lowest lumbar vertebra and the top of the sacrum. Occasionally, there are abnormal tufts of hair on the skin of the involved area. Spina bifida can be a minor bony abnormality without symptoms. However, the condition can also be accompanied by serious nervous abnormalities of the lower extremities.
The condition is cauda equina syndrome. It involves “acute loss of function of the neurologic elements (nerve roots) of the spinal canal below the termination (conus) of the spinal cord,” where the nerves spread out like a horse (equina) tail. Again, this condition causes symptoms in the “saddle” of the body: butt, groin, inner thighs. BACK TO TEXT
It is not clear whether men or women have higher rates of low back pain.[7][8] A 2012 review reported a rate of 9.6% among males and 8.7% among females.[8] Another 2012 review found a higher rate in females than males, which the reviewers felt was possibly due to greater rates of pains due to osteoporosis, menstruation, and pregnancy among women, or possibly because women were more willing to report pain than men.[7] An estimated 70% of women experience back pain during pregnancy with the rate being higher the further along in pregnancy.[97] Current smokers – and especially those who are adolescents – are more likely to have low back pain than former smokers, and former smokers are more likely to have low back pain than those who have never smoked.[98]
Your hip labrum is a band of cartilage-like tissue that courses around the outer rim of your hip socket. This labrum helps to support the joint and deepen the socket. Sometimes overuse or an injury to your hip can cause a tear in your labrum. A hip labrum tear may result in a condition called femoroacetabular impingement (FAI). When this happens, hip pain may result, and exercises to stretch and stabilize your hip may be performed.
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.
As has been highlighted by research presented at the national meeting of the American College of Rheumatology, a very important aspect of the individual evaluation is the patient's own understanding and perception of their particular situation. British researchers found that those who believed that their symptoms had serious consequences on their lives and that they had, or treatments had, little control over their symptoms were more likely to have a poor outcome. This research points out to physicians the importance of addressing the concerns and perceptions that patients have about their condition during the initial evaluations.
Behavioral therapy may be useful for chronic pain.[16] There are several types available, including operant conditioning, which uses reinforcement to reduce undesirable behaviors and increase desirable behaviors; cognitive behavioral therapy, which helps people identify and correct negative thinking and behavior; and respondent conditioning, which can modify an individual's physiological response to pain.[17] The benefit however is small.[91] Medical providers may develop an integrated program of behavioral therapies.[17] The evidence is inconclusive as to whether mindfulness-based stress reduction reduces chronic back pain intensity or associated disability, although it suggests that it may be useful in improving the acceptance of existing pain.[92][93]
The hip flexors play an important role in everyday mobility and exercise. Involved in pulling the knee toward the hip, most movements either directly or indirectly use the hip flexors. That’s why even the slightest injury can cause great discomfort. Learn how you can recover from a hip flexor injury, and what precautions can be taken to avoid them.
A recent study from Florida Atlantic University found that doing 45 minutes of chair yoga twice per week reduced pain and improved overall quality of life in older adults with osteoarthritis. Chair yoga is practiced sitting in a chair or standing while holding the chair for support, so it’s a great option for beginners or anyone dealing with an injury or balance problems.
Just because your hip flexor region feels sore doesn’t necessarily mean the muscles there are tight — in fact, they might need strengthening. This is where that sports science debate we mentioned earlier comes into play. It’s important to identify whether you’re tight or if the muscles are weak. Again, the Thomas Test will help you identify if you’re maybe stretching something that actually needs strengthening.

This stretch gets at the piriformis muscle of the hip flexor. Sit with both legs extended in front of you. Bend the right knee and place the right foot on the floor. Place your right hand behind you and hook your left elbow on the outside of the right knee. As you twist toward the righthand side, keep your spine straight and breathe deeply. Switch sides after about 20 seconds.
Quick anatomy lesson. When we talk about the hips, we're talking about any muscle that crosses over the hip joint, says Laura Miranda D.P.T., M.S.P.T., C.S.C.S., a New York City-based trainer and creator of the Pursuit training program. Which, there are many, including all of the glute muscles, the hamstrings, the inner thigh muscles, and the psoas muscles (deep core muscles that attach your pelvis to your spine). Each of these muscles has some specific roles, but overall, the hip muscles stabilize your pelvis and thighbone as you move. They also allow you to bend at the hips, lift your legs out to the side (abduct), and bring your legs back in toward one another (adduct). Basically, they do a lot, and when they're weak or tight or otherwise not working in an optimal way, you can not only end up with cranky hips, but other body parts may overcompensate and take on too much work—leaving you with other, seemingly unrelated, issues, like knee pain.
The symptoms can also be classified by duration as acute, sub-chronic (also known as sub-acute), or chronic. The specific duration required to meet each of these is not universally agreed upon, but generally pain lasting less than six weeks is classified as acute, pain lasting six to twelve weeks is sub-chronic, and more than twelve weeks is chronic.[3] Management and prognosis may change based on the duration of symptoms.

When a muscle contracts, it shortens. Take the biceps for example. Without getting too technical, the biceps are attached at the forearm and shoulder. When your biceps contract, they shorten and bring those two points closer together. When you rest, the muscle returns to its normal length, and the two points move farther away. Constantly contracting your biceps over a long period of time would cause them to get shorter, even at rest.


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.
Behavioral therapy may be useful for chronic pain.[16] There are several types available, including operant conditioning, which uses reinforcement to reduce undesirable behaviors and increase desirable behaviors; cognitive behavioral therapy, which helps people identify and correct negative thinking and behavior; and respondent conditioning, which can modify an individual's physiological response to pain.[17] The benefit however is small.[91] Medical providers may develop an integrated program of behavioral therapies.[17] The evidence is inconclusive as to whether mindfulness-based stress reduction reduces chronic back pain intensity or associated disability, although it suggests that it may be useful in improving the acceptance of existing pain.[92][93]
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.
