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.

A healthy diet is important for a number of reasons when you have lower back pain. First, eating well can help you maintain a healthy weight. Excess weight puts extra strain on your lower back, adding to your pain. Second, a diet that’s high in key nutrients can help promote bone growth and keep your bones strong. These must-have nutrients include:

Initial management with non–medication based treatments is recommended.[6] NSAIDs are recommended if these are not sufficiently effective.[6] Normal activity should be continued as much as the pain allows.[2] Medications are recommended for the duration that they are helpful.[13] A number of other options are available for those who do not improve with usual treatment. Opioids may be useful if simple pain medications are not enough, but they are not generally recommended due to side effects.[4][13] Surgery may be beneficial for those with disc-related chronic pain and disability or spinal stenosis.[14][15] No clear benefit has been found for other cases of non-specific low back pain.[14] Low back pain often affects mood, which may be improved by counseling or antidepressants.[13][16] Additionally, there are many alternative medicine therapies, including the Alexander technique and herbal remedies, but there is not enough evidence to recommend them confidently.[17] The evidence for chiropractic care[18] and spinal manipulation is mixed.[17][19][20][21]

Disk tear. Small tears to the outer part of the disk (annulus) sometimes occur with aging. Some people with disk tears have no pain at all. Others can have pain that lasts for weeks, months, or even longer. A small number of people may develop constant pain that lasts for years and is quite disabling. Why some people have pain and others do not is not well understood.
Pain along the inside of the hip may be due to tendinitis or strain of the adductor muscles. Adductors (or inner thigh muscles) pull the leg inward as it is moving forward—the faster the movement, the greater the degree of adduction. Since footprints of a runner are almost single file as opposed to the side-by-side footprints of a walker, there is some degree of adduction occurring during running.

If your hips are killing you, you probably spend a lot of time sitting – in the car, at work, on that spinning seat – which puts your hips in near-constant “flexion”, says Cori Lefkowith, NASM-certified personal trainer and owner of Redefining Strength in Orange County, California. Even running involves a repetitive flexion movement that can cause pain. 

The treatment of hip pain depends on the precise cause of the pain. Treatments can include rest, non-weight-bearing, cold application, and anti-inflammatory medications. For local inflammation, sometimes injection of cortisone medication (steroids) is used to quiet the inflammation. If infection is present, antibiotics are used. Fractures can require treatment with surgical repairs, including pinning, plates and screws, and total joint replacement. For severe arthritis, total joint replacement is performed when possible.

When intervertebral disks collapse and osteoarthritis develops, your body may respond by growing new bone in your facet joints to help support the vertebrae. Over time, this bone overgrowth (called spurs) can lead to a narrowing of the spinal canal. Osteoarthritis can also cause the ligaments that connect vertebrae to thicken, which can narrow the spinal canal.

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.

Low back pain (LBP) is a common disorder involving the muscles, nerves, and bones of the back.[4] Pain can vary from a dull constant ache to a sudden sharp feeling.[4] Low back pain may be classified by duration as acute (pain lasting less than 6 weeks), sub-chronic (6 to 12 weeks), or chronic (more than 12 weeks).[3] The condition may be further classified by the underlying cause as either mechanical, non-mechanical, or referred pain.[5] The symptoms of low back pain usually improve within a few weeks from the time they start, with 40–90% of people completely better by six weeks.[2]
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.

This Australian study concluded that “prognosis is moderately optimistic for patients with chronic low back pain,” contradicting the common fear that any low back pain that lasts longer than 6-9 weeks will become a long-term chronic problem. This evidence is the first of its kind, a rarity in low back pain research, a field where almost everything has been studied to death. “Many studies provide good evidence for the prognosis of acute low back pain,” the authors explain. “Relatively few provide good evidence for the prognosis of chronic low back pain.”
The hip joint is designed to withstand a fair amount of wear and tear, but it’s not indestructible. For example, when you walk, a cushion of cartilage helps prevent friction as the hip bone moves in its socket. With age and use, this cartilage can wear down or become damaged, or the hip bone itself can be fractured during a fall. In fact, more than 300,000 adults over 65 are hospitalized for hip fractures each year, according to the Agency for Healthcare Research and Quality.
In both younger and older patients, vertebral fractures take weeks to heal with rest and pain relievers. Compression fractures of vertebrae associated with osteoporosis can also be treated with a procedure called vertebroplasty or kyphoplasty, which can help to reduce pain. In this procedure, a balloon is inflated in the compressed vertebra, often returning some of its lost height. Subsequently, a "cement" (methymethacrylate) is injected into the balloon and remains to retain the structure and height of the body of the vertebra. Pain is relieved as the height of the collapsed vertebra is restored.
