Tendonitis

Tendonitis is a common musculoskeletal condition characterized by inflammation or irritation of a tendon, the thick fibrous cord that connects muscle to bone. It typically develops due to repetitive motion, overuse, or sudden injury, making it prevalent among athletes, manual workers, and individuals with physically demanding routines. Common sites affected include the shoulders, elbows, wrists, knees, and heels, such as in Achilles tendon involvement.

Symptoms often include localized pain, tenderness, mild swelling, and stiffness, especially during movement. The pain may gradually worsen if the affected tendon continues to be stressed without adequate rest. Risk factors include aging, poor posture, improper technique during physical activity, and certain underlying conditions like diabetes or rheumatoid arthritis.

Diagnosis is usually based on clinical examination, though imaging tests like ultrasound or MRI may be used in persistent cases. Treatment primarily focuses on rest, ice application, compression, and elevation (RICE), along with nonsteroidal anti-inflammatory drugs. Physical therapy helps strengthen surrounding muscles and improve flexibility. In severe or chronic cases, corticosteroid injections or surgical intervention may be considered. Preventive measures include proper warm-up, ergonomic adjustments, and gradual progression in physical activities.
