Pain and red marks on Breast after a year of finishing treatment

I had Lumptectomy last April and ANC - followed by Chemo, rads and now on Anastrozole. I had a clear mammogram in March of this year. At the moment I am finding it really hard to sleep from pain in my breast, it is impossible to lie on it at all. It aches nearly all the time and above the nipple are red marks (not raised at all) almost as if someone has scribbled on me! Has anyone else experience this. I know there can be nerve damage after the Rads but this is worst it has been. Could it be because the weather is getting hotter and the sun is getting on my skin perhaps (I am not exposing my boob though) ;-).
Any advice would be greatly appreciated
