Bursitis is inflammation of the fluid-filled sacs, called bursa, that cushion areas of pressure between joints, muscles, and tendons. Bursitis is due to overuse or repetitive actions around the joints of the body. This inflammation results in pain that is experienced during movement or pressure. Treatment involves performing stretches and strengthening exercises to help relieve pressure from the bursa.
Degenerative Conditions: Sometimes, degenerative conditions that are the normal result of aging may cause your low back pain. Conditions like spinal stenosis, arthritis, or degenerative disc disease can all cause pain. Congenital conditions, like spondylolisthesis or scoliosis, can also cause your back pain. For most degenerative back problems, movement and exercise have been proven to be effective in treating these conditions. A visit to your physical therapist can help you determine the correct progression of back exercises for your specific condition.
^{Meanwhile, it’s extremely common for non-life-threatening low back pain to be alarmingly severe and persistent — to have a loud bark! Your doctor may not appreciate how true this is, and may over-react to all persistent low back pain, even without other red flags. In most cases, you shouldn’t let them scare you. Being “freaked out” about persistent back pain is the real threat: it can make low back pain much worse, and much more likely to last even longer (a tragic irony).}
Iliopsoas syndrome, which is also called psoas syndrome or iliopsoas tendonitis, occurs when the iliopsoas muscles are injured. Lower back pain is the most common symptom; however, pain can also occur in the hip, thigh, or leg. The iliopsoas bursa, which is a fluid-filled sac located on the inside of the hip that reduces rubbing and friction, is also likely to become inflamed due to the proximity of the two structures. When this happens, the inflamed bursae will make it difficult to move.
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:

^{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.)}

Lay on your back on your mat and pull your knees to your chest. Place your hands on the inside arches of your feet and open your knees wider than shoulder-width apart. Keeping your back pressed into the mat as much as possible, press your feet into hands while pulling down on feet, creating resistance. Breathe deeply and hold for at least 30 seconds.

_{If you have hip arthritis, work on building up the muscles in your outer thigh for added support. Lie on your pain-free side and lift the leg with arthritis up about six inches, hold for two or three seconds, and lower it again, Humphrey says. Start with one set of 10 repetitions and build up to three sets. Repeat on the other side unless it is too painful. This exercise can aggravate your symptoms if you have hip pain from bursitis.}
^{Kneel on your mat with thighs perpendicular to the floor and tops of of your feet facing down. Place a yoga block between your feet. Bring your inner knees together. Slide your feet apart so they are slightly wider than your hips, and press the tops of your feet evenly into the mat. Slowly sit down on the yoga block. Use your hands to turn the top of your thighs inward. Allow the backs of your hands to rest on your thighs. Hold for at least 30 seconds.}

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.
