Bursitis is a painful condition resulting from inflammation of a bursa. Normally smooth and slippery, the bursa becomes swollen and inflamed creating a rough surface that causes much friction when moved.
Bursitis can be caused by repetitive movement, prolonged excessive pressure, or traumatic injury such as a car accident or a fall. An underlying condition such as rheumatoid arthritis can also make patients more susceptible to developing bursitis. Bursa that become infected may cause septic bursitis.
Common types of bursitis include elbow bursitis, shoulder bursitis, hip bursitis, and node.
