ยง The condition
What is tendonitis?
Tendonitis is inflammation of a tendon, the tissue connecting muscle to bone. In the foot and ankle, the most commonly affected tendons are the Achilles, posterior tibial, peroneal, and extensor tendons. Symptoms include pain that worsens with activity, stiffness after rest, swelling, and tenderness along the tendon. Without treatment, the condition typically becomes chronic and harder to resolve.
