Bursitis, tendinitis, and other soft tissue diseases such as myofascial syndrome, are rheumatic diseases that affect the tissues and structures that surround a joint and produce pain, swelling or inflammation.
Syndromes are groups of signs and symptoms that occur together.
Bursitis is inflammation of the bursa, the small fluid-filled sac that acts like a cushion between muscles and tendons, or between muscles and bones. Tendinitis is inflammation of the tendon, which attaches muscle to bone. Your doctor will perform a physical exam to find where the pain is and to inspect other joints. The specific exam depends on which area of the body is affected. Many of these conditions go away on their own.
