Hi,
Bursitis of the hip refers to the inflammation of the fluid filled sac that surrounds the hip joint.
Bursitis of the hip is most commonly without any infection.
Noninfectious or aseptic hip bursitis can be treated with ice compresses, rest, and antiinflammatory medications. Occasionally, it requires aspiration of the bursa fluid. For severe cases an injection of cortisone medication, often with an anesthetic, into the swollen bursa may help too. Other things that help include weight reduction, stretching exercises, and wearing proper footwear for exercise activities. Bursitis with infection (Septic bursitis) is uncommon and requires antibiotic therapy, often intravenously. Sometimes surgical drainage and removal of the infected bursa sac (bursectomy) may also be necessary.
