What is bursitis?
Bursitis (say: “burse-eye-tiss”) is the painful swelling of bursae. Bursae are fluid-filled sacs that cushion your tendons, ligaments and muscles. When they work normally, bursae help the tendons, ligaments and muscles glide smoothly over bone. But when the bursae are swollen, the area around them becomes very tender and painful. Trochanteric (say: “tro-can-tair-ick”) bursitis is swelling affecting the bursae of the hip.
Bursitis does not only happen in the hip. It can also occur in the shoulder, knee and elbow joints. Bursitis may be acute (short-lived) or chronic (long-lasting).
