Bursitis
Bursitis is the condition that occurs when a bursa becomes inflamed or infected.
A bursa is a sac with a potential space that makes it easier for one tissue to glide over another.
There are approximately 160 bursae in the body but only a few of them become clinically affected.
Most bursae differentiate during development, but new ones may form in response to stress, inflammation, or trauma.
Occasionally, a bursa may communicate with a nearby joint.
