Mr Brightside I too pronate inward slightly and had problems with my left knee, the pain ran from the outside of the knee up into my ITB. I saw both a physio and a podiatrist and with the help of both my injuries have now gone. If like me the problem is stemming from your feet the trouble may well lie with the ligaments/tendons that run under your feet. They may well be tight, if so they need to be stretched, get yourself a golf ball and whilst standing roll the ball around underneath your feet whilst applying pressure (yes, it will hurt!). Another good stretch is to to stand at the bottom of your stairs and push your toes up against the bottom tread so your toes are at a right angle with the floor and the sole of your foot is flat on the floor (hope that makes sense) and then lean forward.

Hope this helps.
