It was all going so well.

HPV16 tonsil cancer - treatment finished January 23.

It was all going so well. The cancer MRI showed all clear, I was getting fitter, was back at work, and had even been on two holidays in England. Then last Monday at work I got up from my chair and my knee gave way. Today I saw a physiotherapist who is sending me for an MRI to assess a miniscus tear in my knee. 

They feel that because of radiotherapy it has weakened my cartilage. Has anyone else experienced this.
