Finally bit the bullet and made an appointment with a sports physio as I am unable to run atm. Tendonitis in my foot - very painful toes are lower foot.
Chap took a quick look and poke at my foot and straight away said 'your problem isn't in your toes, it's here' massaging the top of my foot/lower shin. Nearly has to scrape me off the ceiling! I'd never have beleived it TBH. Had some electro therapy and massage and been told to dunk my foot in hot water, and then cold water for 2 mins each for 20 minutes. Going back on Friday. When it's less painful he will teach me some massage techniques. He says he won't see me too much as it's down to me to treat it mostly - with massage and the hot/cold water thing.
Hurts like hell right now but hoping that's a good sign .
