Mr Patient

Patient: Hi thereI have a really hard bump on the inside of my left knee. It was due to a rugby injury which I thought was just a bruise and swelling. It is now 2 months later and the bruise and swelling have gone down but there is still this hard (feels like bone) bump. It hurts to push on it, but I have no trouble walking. Every time is sit down for a bit or lie down and then stand up it makes like a clicking noise and when I walk it feels like it is grinding on something. It is particularly sore in the morning and evening.Thanks very much
