I hit my knee really hard last Tuesday and is bruised and painful and swollen, I had an x-ray and the patella is fine, but they refused an MRI s the Nhs hospital don t do that, so they couldn t see whether I have damaged any soft tissue , as I had a previous arthroscopy on the same knee I am quite anxious , do u think if there is any chance if I hurt my cartilage or meniscus? Thanx
