Yes I had the same thing happen to me. My surgery was Nov 2023 radiation was completed in Jan 2024. I had 23 treatments done to my right. They removed 3 nodes and lumpectomy was done also. It’s tight all the time. I do stretches and wear a sports bra to sleep in as well. My doctor told me it’s still going to be sore because the inside is still healing from the surgery and radiation. Hope this helps.
