I am 2 years past my radiation and I still get PT for my pectorial. Radiation changed the elasticity of the muscle. They said it's just part of radiation. It is a total drag and it always feels tight. I had a recurrence in my lymphnodes and had an axillary disection so I have a lot of numbing as well. The tightness is always there and sometimes pulls of the scar which feels like burning or an abrasion that you get on your palms. I do streches all the time and I have had improvement through the last two years. I know this doesn't sound positive and somedays I feel absolutely deflated from it but I am grateful that I am alive still. I just have to work extra hard.
