I think i have the above. When i run i have pain on the outside of my knee normally my left. Some times it is very painful, sometimes i dont even know its there. 3 months ago I went to a proper running shop to get my gait analysed, no problems. The pain has started getting more frequent but does come and go. I dont get any hip pain or glute discomfort. I have a doctors appointment monday who will probably tell me there's nothing wrong. I dont have any pain walking, rowing, cycling, swimming or up stairs, only very sometimes downstairs (if inflamed i guess) Any advise, i have my RPC (RNAC) november 8th and i must keep running as its my weakest subject.
