How to treat peroneal tendonitis?

This can be treated with physical therapy, medications, injections, bracing like taping. Often it is associated with an underlying unlying condition in the back, feet, or ankles. See a doctor

Hi, I recommend discussing with the doc who made ur diagnosis, but in general: first u should limit activities that cause or worsen the pain, for example running. Second apply ice and heat (brief application) alternating. Third use anti-inflammatory if your health will allow that. 4th immobilization such as a orthotic or cam boot. Ultimately u may need PT, injections, or LASTLY surgery.
