Hi there, Recently I had a knee injury, at first I thought it was simply runners knee, but after a few weeks ago it hadn't gone and was still hurting, not constant pain, it comes and goes. I spoke to a nurse (who wasn't qualified, but had spent 3 years working in orthopaedics) who told me it would be a problem for life. She put me on anti-inflams for 5 days (ago), and things are a lot better now, although I can feel it's not yet healed. I have booked a appointment with the best specialist I can find. But my question, assuming this is a problem for life, could I still join up? - I can still run no problems at all.
