Peroneal Tendonitis
Description
This is a painful inflammation of the peroneal tendons. These tendons travel from the lower leg to the foot. They pass along the outer side of the ankle. Without proper care, this injury can turn into a long-term problem we call “peroneal tendinosis.”

Causes & Triggers
What causes these tendons to become inflamed? It’s linked to overuse. It can happen to new runners, and to runners who increase their run times. It can happen to athletes who play sports that require a lot of quick pivots. It’s more common in people who have high arches, and in those who have had a lot of ankle sprains. And, it can be linked to shoes that don’t give you good support.
- Overpronation (inward rolling) of foot
- Overuse or repetitive overloading
- Tight calf muscles
Signs & Symptoms
What are the symptoms? You may have pain and swelling. This can affect the area below and behind the bony bump on the outer side of your ankle. Your pain may get worse with activity, and improve with rest.
- Irritation or inflammation
- Morning pain
- Pain or discomfort outside ankle, behind the bony protrusion
- Pain with new or increasing activity
Tips & Treatment
How do we treat it? We commonly start with rest, and possibly a walking boot. You may benefit from medications and physical therapy. If these don’t help, you may need surgery. Your doctor will create a plan that’s right for you.
- Most patients cannot recall injuring themselves; the area is simply painful.
- Irritation can range from mild to moderate to severe, depending on whether tendon is torn, split or dislocated.
- Diagnostic testing is required for proper diagnosis and may include MRI.
