Overuse/Compensation: Peroneal tendonitis is an inflammation of the tendon and tendon sheath complex of the peroneus longus and brevis tendons. These tendons arise from muscles in the outside of the lower leg and course behind the fibula (ankle bone on outside of ankle). Walking on the outside of the foot (often to avoid pain on the inside of the foot or heel) can lead to this condition as can a bad ankle sprain.
