Just an update:
The ointment/ cream that the radiation doc prescribed for me is called Fluticasone .05% cream...generic for Cutivate .05%. It did the job and it's all dried up now!! YAY! I wanted to pass this on for any of my sisters/ brothers who is, or might suffer the same. It dried it up in about a week. I still have a bit of itching, but I think that is due to the dried rash bumps.
Thank you all sooo much for your concern, thoughtfulness, and suggestions. It is always greatly appreciated and this is like a big family :) Hugs to all :)
