A couple of weeks ago I uncharacteristically did some quite full on exercise. I was fine at first, a bit sore, then I had several busy days where I was on my feet for very long periods, running around, carrying heavy equipment up and down stairs. Since then I've had severe pain when walking and occasionally at other times on the inside of my shins. It feels like it's getting worse rather than improving. Is there anything I can do to speed up recovery and stop hobbling around everywhere? I had hoped to be doing more exercise but there's no chance of that at the moment.
