What Is Peroneal Tendonitis?

Peroneal tendonitis is the inflammation of one or both peroneal tendons, which run along the outside of the ankle and foot. These tendons help stabilize the ankle and foot during movement. Repetitive stress, overuse, or poor footwear can strain the tendons, leading to swelling and pain.

Common Symptoms:

  • Pain along the outer ankle or foot

  • Swelling and tenderness

  • Pain that worsens with activity

  • Weakness or instability when walking or running

  • Stiffness or discomfort after periods of rest

What Causes It?

  • Overuse from sports or activity

  • Sudden increase in exercise

  • High arches or poor foot biomechanics

  • Inadequate footwear or unsupportive shoes

  • Ankle sprains or past injuries

How We Treat Peroneal Tendonitis at Third Coast Foot & Ankle

Our goal is to reduce inflammation, relieve pain, and prevent the issue from recurring. Your treatment may include:

  • Custom Orthotics – Support proper foot alignment and reduce tendon strain

  • MLS Laser Therapy – A non-invasive treatment that reduces inflammation and speeds healing

  • Physical Therapy – Improve strength, flexibility, and movement patterns

  • Immobilization (if needed) – A short period in a boot or brace may allow the tendon to rest and heal

  • Shockwave Therapy – Stimulates blood flow and tissue regeneration for chronic cases

  • Activity Modifications – We’ll guide you on how to stay active while allowing healing

Don’t Wait—Early Treatment Prevents Long-Term Damage

Without proper care, peroneal tendonitis can lead to tendon tears or chronic ankle instability. The sooner we evaluate and treat the condition, the faster you’ll return to your normal activity—pain-free.
