What it means
Tendinitis is inflammation or irritation of a tendon—the thick fibrous cords that attach muscle to bone. It most often results from repetitive motions or sudden injury and commonly affects the shoulder, elbow, wrist, knee, and heel. Pain is usually a dull ache near the affected joint, worsening with movement. Tenderness and mild swelling at the site are common. While most people recover with rest, ice, and anti-inflammatory medications, chronic tendinitis can progress to a tendon tear if untreated. Physical therapy, eccentric exercises, and occasionally corticosteroid injections are standard treatments.
