I walked 7 miles on Monday in flat flimsy shoes and since then I've been unable to walk without limping as the outer part of my left foot is very painful. I can stand and put weight on it no problem but as soon as I walk then i'm in a lot pain. painkillers don't help much and nor does icing the foot. Has anyone experienced this before and do you have any suggestions? I'm not sure whether to go to GP or hope that it eventually goes away...
