Please don't laugh at this, but my radiation therapist told me to use "Bag Balm" (yes, as in a cow's udder bag) to aid in the soreness of radiation burns and ulcers. It took my wife going to four or five places, but at a local feed store, they had the balm and I have been using it since. It is wonderful, scentless, and lasts for hours and hours. My wife says her hands are much softer after helping apply my stuff to me. You might give it a try. Good luck and God Bless!!
