^{People routinely have no pain despite the presence of obvious arthritic degeneration, herniated discs, and other seemingly serious structural problems like stenosis and spondylolistheses. This surprising contradiction has been made clear by a wide variety of research over the years, but the most notable in recent history is Brinjikji 2015. There are painful spinal problems, of course — which was also shown by Brinjikji et al in a companion paper — but they are mostly more rare and unpredictable than most people suspect, and there are many fascinating examples of people who “should” be in pain but are not, and vice versa. Spinal problems are only one of many ingredients in back pain. BACK TO TEXT}
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.

Radicular pain. This type of pain can occur if a spinal nerve root becomes impinged or inflamed. Radicular pain may follow a nerve root pattern or dermatome down into the buttock and/or leg. Its specific sensation is sharp, electric, burning-type pain and can be associated with numbness or weakness (sciatica). It is typically felt on only one side of the body.

Sacroiliac joint dysfunction. The sacroiliac joint connects the sacrum at the bottom of the spine to each side of the pelvis. It is a strong, low-motion joint that primarily absorbs shock and tension between the upper body and the lower body. The sacroiliac joint can become painful if it becomes inflamed (sacroiliitis) or if there is too much or too little motion of the joint.
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.
There are many tendons located around the hip that connect the muscles to the joint. With various activities or overuse, these tendons can become inflamed. This inflammation results in pain around the hip region. Iliotibial band syndrome is one of the most common causes of tendonitis at the hip joint. The hallmark of this condition is pain on the lateral, or outside, aspect of your hip.

Brace your core and bend your knees to lower down into a split squat. Your left knee should ideally form a 90-degree angle so that your thigh is parallel to the ground, and your right knee is hovering above the floor. (Quick position check: your left foot should be stepped out far enough that you can do this without letting your left knee go past your left toes—if you can't, hop your left foot out a bit farther away from the bench.)
Start in a runner’s lunge, right leg forward with knee over ankle and left knee on ground with top of your foot flat on the mat. Slowly lift torso and rest hands lightly on right thigh. Lean hips forward slightly, keeping right knee behind toes, and feel the stretch in the left hip flexor. Hold here, or for a deeper stretch, raise arms overhead, biceps by ears. Hold for at least 30 seconds, then repeat on opposite side.
Simply stand up straight with your feet about shoulder-width apart. Slowly bend your knees and hips, lowering yourself until your knees obscure your toes or you achieve a 90 degree angle. Hold for a count of 5 and then gently resume your original position. This can be a tough one so again, don’t overdo it and hold on to a table if you need a little extra support! Try to repeat between 5-10 times.
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.

Other problems may occur along with low back pain. Chronic low back pain is associated with sleep problems, including a greater amount of time needed to fall asleep, disturbances during sleep, a shorter duration of sleep, and less satisfaction with sleep.[24] In addition, a majority of those with chronic low back pain show symptoms of depression[13] or anxiety.[17]

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.

Kidneys — The kidneys are a matched pair. One painful kidney can cause back pain on one side or the other. Kidney pain can feel like back pain, and may occur on only one side. It is usually quite lateral, and just barely low enough to qualify as “low” back pain. However, when kidney stones descend through the ureters, they can cause (terrible) pain in the low back. Kidney stone pain is often so severe and develops so rapidly that it isn’t mistaken for a back pain problem.
Exercise appears to be useful for preventing low back pain.[47] Exercise is also probably effective in preventing recurrences in those with pain that has lasted more than six weeks.[1][48] Medium-firm mattresses are more beneficial for chronic pain than firm mattresses.[49] There is little to no evidence that back belts are any more helpful in preventing low back pain than education about proper lifting techniques.[47][50] Shoe insoles do not help prevent low back pain.[47][51]
_{Strong muscles support and protect your joints. “Strengthening the lower body takes some of the pressure off of the hip and knee joints,” says William Oswald, DPT, a physical therapist and clinical instructor of rehabilitation medicine at NYU Langone Health. This can relieve some of the pain and protect against more damage. “It can also make daily tasks, such as climbing the stairs, easier,” he says.}
For example, your quadriceps muscles are a group of four that are located at the front of the thigh; one of the group members, the rectus femoris flexes the hip, which brings your lower extremity (thigh, lower leg, and foot) forward, in front of you. On the other hand, your hamstring muscles are located at the back of the thigh. When they contract, they extend the lower extremity, bringing it behind you.

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.
Traction involves the use of weights and pulleys to apply constant or intermittent force to gradually “pull” the skeletal structure into better alignment. Some people experience pain relief while in traction, but that relief is usually temporary. Once traction is released the back pain tends to return. There is no evidence that traction provides any longterm benefits for people with low back pain.
Since the hip flexors are so easy to overuse and strain, it is important to stretch them before exercise or strenuous activity. Because of their connectedness to other muscle groups in the legs (like the quadriceps), it is important to stretch the muscle group as a whole, not individually. This ensures that the entire area is warmed up and ready for the strain of exercise or activity, not just one or two individual muscles.

Treatment options include physical therapy, back exercises, weight reduction, steroid injections (epidural steroids), nonsteroidal anti-inflammatory medications, rehabilitation and limited activity. All of these treatment options are aimed at relieving the inflammation in the back and irritation of nerve roots. Physicians usually recommend four to six weeks of conservative therapy before considering surgery.

Vertebroplasty and kyphoplasty are minimally invasive treatments to repair compression fractures of the vertebrae caused by osteoporosis. Vertebroplasty uses three-dimensional imaging to assist in guiding a fine needle through the skin into the vertebral body, the largest part of the vertebrae. A glue-like bone cement is then injected into the vertebral body space, which quickly hardens to stabilize and strengthen the bone and provide pain relief. In kyphoplasty, prior to injecting the bone cement, a special balloon is inserted and gently inflated to restore height to the vertebral structure and reduce spinal deformity.
