Redness and burning is pretty common. In many cases, it does get as bad as it is going to get maybe 1/2 or 2/3rds of the way into treatment. If it become more painful or the skin starts cracking and bleeding, let you radiation oncologist know right away. He/she might be able to prescribed something for the pain or suspend treatment for a few days until any skin breaks heal.

I had 34 treatments and i had a place come up closer to neck area. I told my doctor about it and he prescribed a compound ointment that soothed the burn area and also had a pain reliever in it. So talk to your doctor about it.

Mine curled under my arm and for several weeks I couldn't rest my arm at my side; I had that hand on my hip and elbow flared out at all times.

I used the aquaphor daily. Sometimes more than daily. I was also, near the end, prescribed an antibiotic cream to apply.

A year later, my square of radiation is still a different color. The skin still has little elasticity.

I agree with the earlier comments: continue to keep your radiation oncologist appraised of any changes that occur.
