I had radiation 9 years ago for colorectal cancer. I got radiation burns in my pelvic area. I tried every cream imaginable, but nothing worked. A man that worked at the radiation clinic said to try diluted peroxide. Sure enough, it healed my "crotch" in a couple days and was very inexpensive. I don't know if the dilute peroxide would help inching, but it would be worth a try. Many prayers to you during this difficult time.
