Peroneal Tendonitis

I’ve been dealing with ankle pain for over a month now, trying to get in with a doc but having a hard time finding somewhere that doesn’t book out super far! Any tips on how to deal with likely Peroneal tendonitis? I’ve been biking which does not cause any pain. It hurts slightly when walking, but gets worse after running (which is why I’ve taken ~a month off). I recently got bands to do some ankle exercises, but have not noticed a huge difference yet. I would be grateful for any suggestions!
