If you experience pain on the outside of your foot or leg you may be experiencing Peroneal Tendinopathy. A common cause of this is an injury to the peroneal tendon. The peroneal tendon supports the ankle and helps pronate the foot (roll the foot in).
We have two peroneal muscles that work together to stabilize the foot and ankle. The larger peroneal tendon is called the Peroneal Longus and the shorter peroneal tendon is called the Peroneal Brevis. The peroneal muscles start in the outer leg before turning into tendons as they run around the outside aspect of the ankle. Both tendons then insert into the lateral aspect of the foot. Pain can be felt at any of these points in the leg, ankle, or foot and could be coming from one of the muscles, or sometimes both.
