What Is Bursitis?
Bursitis refers to the inflammation of a bursa, which can be found throughout the body next to the tendons that are located near large joints including the knees, hips, elbows, and shoulders. Bursae are sacs filled with fluid that function as cushions to reduce friction from movement between tissues. Most of the time, bursitis is a temporary condition that just leads to limited mobility but does not develop into a deformity. Some common types of bursitis include trimalleolar tendon bursitis (located where the tendon attaches to the heels), posterior Achilles tendon bursitis (located between the Achilles tendon and the skin of the heel), elbow bursitis (located between the bones and skin of the elbows), knee bursitis (located between the three tendons of the hamstring and shin bone), kneecap bursitis, and hip bursitis.
