Peroneus Brevis Triggers Ankle Pain

Upon spraining or fracturing an ankle, certain trigger points are developed due to the extra burden placed on the lower leg muscles. The problem with these trigger points is, they exist even after the ankle heals. These trigger points flare up every now and then causing pain and ankle weakness.

These trigger points are also produced in the muscle peroneus brevis. Thus, peroneus brevis triggers ankle pain.

Peroneus Brevis Triggers Ankle Pain: The development of trigger points is bound to cause pain despite there being no sprain or an injury or a fracture.

There are three muscles possessing trigger points that cause the ankle pain. They are:

  • Peroneus Brevis
  • Peroneus Longus
  • Peroneus Tertius

The group of above listed peroneal muscles are found just under the knee on the outside of it. These peroneal muscles tend to run into the ankle joint and are connected to the foot’s outside. When these muscles contract they cause foot eversion (keep us from falling).

  • The muscles peroneus longus and brevis trigger pain in the area just behind the ankle bone. Also, they would lead to tenderness which might result in tendon problems. There is every possibility that the pain might extend down to the foot’s outside.
  • The peroneus tertius usually causes the pain in from of the ankle bone. They are also known to cause tenderness and the pain is extended to the foot’s top when the pain is triggered by peroneus tertius.

Associated Risks: As already mentioned peroneus brevis takes care of foot eversion.

  • Upon the development of trigger points in the muscle, they lead to a very weak, tender and unstable ankle.
  • Once the ankle is rendered unstable, the phenomenon of eversion is averted. This causes the ankle to sprain more frequently.
  • The unstable ankles would lead to developing abnormal walking styles which would eventually cause calluses on the heels and on the feet’s outside.

Peroneus brevis triggers ankle pain along with the other group of peroneal muscles. Not much can be done to avoid developing trigger points. But, there are effective treatments available.
