Tendonitis is an inflammation or irritation of a tendon, the thick fibrous cords that attach muscle to bone. This condition often results from repetitive motion, overuse, or injury, leading to pain, swelling, and discomfort in the affected area. Though it can occur in any tendon in the body, common locations include the shoulders (rotator cuff tendonitis), elbows (tennis elbow), knees (jumper's knee), and Achilles tendon. Activities that require repetitive use of these tendons—such as sports, certain occupations, or hobbies—can contribute to the development of tendonitis.
While tendonitis can affect anyone, it’s particularly prevalent among athletes and individuals who engage in repetitive tasks. Treatment typically includes rest, ice, anti-inflammatory medications, and physical therapy to strengthen and stretch the tendon. In some cases, more advanced treatments like corticosteroid injections or surgery may be necessary if conservative measures do not alleviate symptoms. To prevent tendonitis, it’s crucial to warm up properly before physical activities, gradually increase exercise intensity, and allow adequate recovery time between workouts.
