What’s the difference between tendinitis and bursitis?

Overusing one part of your body – like a baseball pitcher’s arm – can lead to tendinitis or bursitis. Tendinitis is irritation of the tendon, a cord-like tissue that secures muscles to bones. Bursitis is inflammation of the bursa.

You may have both conditions at the same time or one or the other. Your healthcare provider can tell which one you have by the location of your pain or by viewing imaging tests.
