I have pain on my left knee, in X-ray everything is fine and normal, I have a strong feeling that l have some nerve or tissue issues. My orthopaedic gave me some pain killer and said if not recovered in 15 days I have to do mri of the knee. And it has been 20 days still it has not recovered. I don't know what will help me, should I continue to visit orthopaedic or I should go to physiotherapist? Please help.
