Arthritis. Osteoarthritis and rheumatoid arthritis are among the most common causes of hip pain, especially in older adults. Arthritis leads to inflammation of the hip joint and the breakdown of the cartilage that cushions your hip bones. The pain gradually gets worse. People with arthritis also feel stiffness and have reduced range of motion in the hip.
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]
Sleeping in an awkward position can cause you to be in pain from the moment you wake up. The best sleeping position for lower back pain may be sleeping on your side with your knees drawn up close to your chest (also known as the fetal position). Placing a pillow or two between your legs, while sleeping on your side, helps to reduce stress on your lower back. Sleeping on a too soft mattress can also cause lower back pain. A firmer mattress is best.
Pregnancy commonly leads to low back pain by mechanically stressing the lumbar spine (changing the normal lumbar curvature) and by the positioning of the baby inside of the abdomen. Additionally, the effects of the female hormone estrogen and the ligament-loosening hormone relaxin may contribute to loosening of the ligaments and structures of the back. Pelvic-tilt exercises and stretches are often recommended for relieving this pain. Women are also recommended to maintain physical conditioning during pregnancy according to their doctors' advice. Natural labor can also cause low back pain.

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.
Endometriosis (when the uterus lining grows somewhere else) can cause pelvic tenderness, which some women describe as hip pain. Pain from the back and spine also can be felt around the buttocks and hip, Siegrist says. Sciatica, a pinched nerve, typically affects one side of the body and can cause pain in the back of the right or left hip — the pain from sciatica can start in your lower back and travel down to your buttocks and legs.
Disc degeneration remains a key cause of chronic low back pain and the pain often persists despite surgery. NIH-funded basic science and preclinical studies are investigating molecular-level mechanisms that cause discs in the spine to degenerate, as well as protective mechanisms involved in disc remodeling that may diminish with advancing age. Such studies may help identify future therapeutic strategies to block degenerative mechanisms or promote remodeling processes. NIH also is funding early research on stem cell approaches to promote disc regeneration and rejuvenate cells of the nucleus pulposus, the jelly-like substance in the center of intervertebral discs that loses water content as people age.

Low and lower back pain can vary from dull pain that develops gradually to sudden, sharp or persistent pain felt below the waist. Unfortunately, almost everyone, at some point during life will experience low back pain that may travel downward into the buttocks and sometimes into one or both lower extremities. The most common cause is muscle strain often related to heavy physical labor, lifting or forceful movement, bending or twisting into awkward positions, or standing in one position too long.
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] 
How to: Position yourself on your hands and knees, in tabletop position. Engage your abs engaged by pulling your belly button in towards your spine (a). Keeping your hips pointed towards the ground and leg bent to a 90-degree angle, raise your left knee out to the side as high as you can (b). Pause at the top, then return to starting position (c). Repeat, then switch legs.
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.
