Tendinopathy is a condition involving pain, swelling, and impaired function of a tendon, often resulting from overuse, repetitive strain, or age-related changes in the tendon tissue. It commonly affects areas such as the shoulder, elbow, knee, and Achilles tendon. Unlike acute tendon injuries, tendinopathy is typically a chronic condition without significant inflammation, characterized instead by tendon degeneration.

Medical treatment focuses on reducing pain, promoting tendon healing, and restoring strength and function. Options may include activity modification, physical therapy with eccentric strengthening exercises, non-steroidal anti-inflammatory drugs (NSAIDs), shockwave therapy, platelet-rich plasma (PRP) injections, or, in persistent cases, referral for surgical evaluation. Early intervention is key to preventing long-term dysfunction.
