I'm having fairly serious pains in my knees (especially the right one) after doing part 1c a few weeks ago (running with weight) and also quite a bit of distance running in the last two years. I've always had slightly iffy knees but 2000mg of glucosamine every day for the past three years has kept them usable. But now its got to the stage over the past few days where i'm struggling to walk and ibupofofen only helps for a few hours at a time. It'll be okay in a few days but if i run again it'll be painful for several days afterwards. There is no way i can do squats or things like that. I'm off to my GP on monday but i suspect that arthroscopic surgery will be needed. Anyone have any idea what waiting times are like for surgery?
