The hip joint is one of the largest and strongest joints in the human body yet it is not immune from pain. One of the most common reported types of hip pain is bursitis (inflammation of the bursa). These fluid-filled sacs are found around the body and serve as cushions between bones and soft tissues such muscles, tendons, and the skin.
Each hip has two major bursae. The outside point of the hip, which is called the greater trochanter, has a bursa called the trochanteric bursa. (The other bursa, on the inside of the hip area, is called the iliopsoas bursa.)
When that outside hip bursa gets irritated, inflamed, and/or painful, you have trochanteric bursitis. It is a common condition and easily treatable. In most cases, bursitis pain goes away within a few weeks with proper treatment, but recurrent flare-ups of bursitis are common.
