I have been having alot of pain in my peroneal tendon. my orthopedic surgeon things that it's just inflamed. i fell yesterday and i cannot walk on it?

Quite Simple.: OH, there is no doubt that it's inflamed. If you cannot walk on it then something else is probably going on too. Either have him re-examine the ankle or it's time to find another specialist.

You need a repeat-: -appointment to have this re-evaluated. It could be a rupture of the tendon or the can dislocate, both are painful and need attention.
