The hip is a very stable ball and socket type joint with an inherently large range of motion. The hip contains some of the largest muscle in the body as well as some of the smallest. Most people lack mobility due to a relatively sedentary lifestyle. Periods of prolonged sitting results in tightness of the hip flexors and hamstrings. Tightness in the muscles and ligaments can created joint forces that result in arthritis, postural problems, bursitis, and mechanical back pain.

There is a significant overlap of nerve supply to many of the discs, muscles, ligaments, and other spinal structures, and it can be difficult for the brain to accurately sense which is the cause of the pain. For example, a degenerated or torn lumbar disc can feel the same as a pulled muscle – both creating inflammation and painful muscle spasm in the same area. Muscles and ligaments heal rapidly, while a torn disc may or may not. The time course of pain helps determine the cause.
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]

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.
Intervertebral disc degeneration is one of the most common mechanical causes of low back pain, and it occurs when the usually rubbery discs lose integrity as a normal process of aging. In a healthy back, intervertebral discs provide height and allow bending, flexion, and torsion of the lower back. As the discs deteriorate, they lose their cushioning ability.

Exercise therapy is effective in decreasing pain and improving function for those with chronic low back pain.[50] It also appears to reduce recurrence rates for as long as six months after the completion of program[61] and improves long-term function.[57] There is no evidence that one particular type of exercise therapy is more effective than another.[62] The Alexander technique appears useful for chronic back pain,[63] and there is tentative evidence to support the use of yoga.[64] Transcutaneous electrical nerve stimulation (TENS) has not been found to be effective in chronic low back pain.[65] Evidence for the use of shoe insoles as a treatment is inconclusive.[51] Peripheral nerve stimulation, a minimally-invasive procedure, may be useful in cases of chronic low back pain that do not respond to other measures, although the evidence supporting it is not conclusive, and it is not effective for pain that radiates into the leg.[66]

In the majority of cases, a hip sprain begins as a microscopic tear that gradually increases in size with repetitive use of the hip. These types of tears are common in sports like cycling, running, swimming, baseball, and golf due to overuse of the hip. If diagnosed early, Grade I and Grade II strains can be effectively treated with rest and other conservative treatments. Grade III strains, however, are one of the most serious hip injuries. This is especially true if the strain is accompanied by a fracture. If your hip cannot bear weight, it is imperative that you contact an orthopaedist for professional treatment.
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]
