The Peroneal muscle group attaches just below the outside of the knee and runs down through the ankle joint and connects to the outside of the foot. When they contract, they raise the outside of the foot (eversion of the foot).The trigger points found in the Peroneus Longus and Brevis produce pain and tenderness just above and behind the outside ankle bone. The pain will sometimes also extend down the outside of the foot.
     Peroneus Tertius trigger points typically produce pain and tenderness on the front of the ankle that extends down on the top of the foot.
     Besides pain, trigger points in these muscles make your ankles feel weak and unstable. This instability will often lead to ankle sprains. Additionally, people often develop calluses on the outside of their feet from abnormal walking mechanics.
Ankle Pain Introduction
     Ankle sprains or fractures will typically overload the muscles in the lower leg, causing them to develop trigger points. These trigger points tend to persist long after the ankle has healed, causing periodic pain flair-ups and general weakness. These trigger points can also produce ankle pain without injury, or any previous sprain or fracture.


The Muscles and Trigger Points that Cause Ankle Pain:
     Trigger points in the following muscles frequently produce ankle pain.
  • Peroneus Longus
  • Peroneus Brevis
  • Peroneus Tertius
