Tendinitis is inflammation of a tendon, a strong fibrous structure that connects muscles to bone. This may develop behind your ankle or on either side of the foot. If symptoms continue to progress or remain untreated, it may ultimately result in rupture of the involved tendon.
These symptoms may develop as a result of overuse, poor biomechanics or foot structure, or trauma. Conservative therapy may involve ice, anti-inflammatories, limitation of activities, physical therapy, rest, bracing, good fitting shoes or custom orthotics. In severe cases, surgery may be required to repair the damaged tendon and/or correct abnormal foot structure.
