Hopefully the shot will work, I had mine just before I came away and at the moment you'd never think anything was wrong with my left knee. We climbed up a steep hill yesterday, quite a long way and I was fine, I couldn't have done that without the cortisone injection. I'm just hoping it will last until I get home. I'm having an arthroscopy in August, I'm sure that things will only get worse then, that's what happened with my right knee, but he won't let me got straight to the TKR with my left.
