The peroneus longus and peroneus brevis muscles are located on the outside of the lower leg. Trigger points in the muscles can cause pain around the outside ankle that goes down into the outside of the foot. TrPs can also contribute to numbness in the outside of the lower leg, ankle, and foot.

    Where Are The Peroneus Longus and Brevis Muscles?

    Peroneus Longus and Peroneus Brevis Muscles Showing Trigger Point Locations
    • Peroneus longus – attaches to the head of the small bone of the lower leg (fibula) running down the outside of the leg. The tendon of the longus then travels behind the outside ankle bone and crosses under the foot to connect to the bones in front of the big toe.
    • Peroneus brevis attaches partway down the small bone of the lower leg (fibula), running down the outside of the leg and connecting to a bone in front of the little toe (metatarsal).

    What Movements Do They Control?

    • Turns the sole foot outward
    • Twists the foot out
    • Assists in pointing the toes down

This brace will give you much-needed support and ease your pain if you have weak ankles and chronic ankle pain.

    What Causes Peroneus Trigger Points To Develop?

    • Twisting the ankle

    Peroneus Muscles Trigger Point Treatment

    To resolve and deactivate trigger points and their associated pain, you need to treat them several times throughout the day. Each treatment takes 1-2 minutes.

    If you are interested in learning how to treat trigger points, The Trigger Point Therapy Workbook is an excellent guide. It includes instructions and diagrams showing muscle locations as well as the trigger point location.

    You can also go to a massage therapist, chiropractor, or physical therapist with training in trigger point therapy. They will be able to show you how to find the TrP and treatment method.

    Sombra Warm Therapy Gel is recommended for relaxing muscles and relieving pain. It warms without the burning heat of other gels. An excellent choice for pain caused by trigger points, muscle/joint over-use and stiffness, and arthritis.

    Biofreeze Pain Relieving Gel is an excellent pain-relieving gel recommend for those who have sudden onset muscle pain or recent injuries.  It is better to use than warm therapy gels and creams for muscle pain caused by inflammation as it cools the area much like ice. If your pain is from a recent injury, use Biofreeze. It is excellent to use on sprains, strained and sore ankles.

    How Long Before I Feel A Reduction In Pain?

    Though it takes time to deactivate the trigger point fully, you will feel some relief immediately. Discomfort eases with each treatment.

    Interesting facts:

    • A tendency of ankle sprains can be an indication of trigger points in the peroneus muscles.
    • Trigger point symptoms are often misdiagnosed as arthritis or tendonitis.
