Hi Sharon, no my “fibrosis” has developed after the radiation. I had no pain during treatment. It is not really incapacitating. I can do what I want to do but the sensation of tightness and slight resistance is always there. Another concerning thing is the development of small little lumps in the skin. They feel like little hard fat lumps?! Doctors don’t express any concern about them, which I suppose is good but they haven’t been able to explain them to me🤔. I find the best exercise for the fibrosis is stretching through yoga poses and playing tennis. Fortunately I am right handed. Wishing you all the best🙏🙏🤗
