Zubis said: Looking for some advice...about a year ago I busted my knee at Christmas. As it was Christmas I left it for a week until I saw a physio-therapist and he said with some exercises and a brace it should be fine. It was - I can walk 10, 20K easily on it. But recently I wanted to try jogging and I can barely get 100m without being in a fair amount of pain. A work colleague says I have impact damage. Should I go back to the physio or go to a Doctor/surgeon first?
