Bursitis, or inflammation of a bursa, is usually not infectious, but the bursa can become
Treatment of noninfectious bursitis includes rest, ice,
and medications for inflammation and pain. Infectious bursitis (uncommon) is
treated with antibiotics, aspiration, and surgery.
Bursitis of the hip is the most common cause of hip pain.
Trochanteric bursitis frequently causes tenderness of the outer hip.

What is bursitis?
A bursa is a closed fluid-filled sac
that functions as a gliding surface to reduce friction between tissues of the
body. "Bursae" is the plural form of "bursa." The major bursae are located adjacent to
the tendons near the large joints, such as the shoulders, elbows, hips, and
knees. When the bursa becomes inflamed, the condition is known as
There are two major bursae of the hip, the trochanteric bursa and the ischial bursa. Inflammation of either can be associated with stiffness and pain around the hip joint. The trochanteric bursa is located on the side of the hip. It is separated significantly from the actual hip joint by tissue and bone. Bursitis is not arthritis and, therefore, is not a cause of true joint pain.

For what conditions are cortisone injections used?
Cortisone injections can be used to treat the inflammation of small areas of the body (local injections), or they can be used to treat inflammation that is widespread throughout the body (systemic injections). Examples of conditions for which local cortisone injections are used include inflammation of a bursa (bursitis of the hip, knee, elbow, or shoulder), a tendon (tendonitis), and a joint (arthritis).
