I had radiation in July of 2010..and I still have a rash and it does itch terribly. If you ask they will give you lotion. The doctor gave me Calendula Lotion..it is Homeopathic and nongreasy. He also gave me Dove for sensitive skin soap.
I had the radiation in the back and in the front for my spine. The front didn't get a rash as bad as the back.
Hope this helps you..it takes time!
Peace and Blessings,
