Breast pain after radiation

Psychknowledge

I was diagnosed with DCIS last year. I had a lumpectomy and then another surgery due to not having clear margins. I ended up with a decent sized seroma (collection of fluid) which delayed radiation a couple of months. I finally had 26 radiation treatments including 6 "boost" sessions. My last radiation treatment was April 24, 2019. I had pain in my breast during radiation. Unfortunately the pain never went away. It is getting a little worse. I have what I call a throbbing pain all of the time. Ibuprofen helps dull It but it never goes away. It also hurts to the touch. Is this expected? Any end in sight? Thanks in advance!
