Neck burnt and peeling

Ace's neck looks like hamburger meat and is hot like a very bad sunburn. He gas had all the radiation treatments.  We are at the bottom of the hill and on our way up now. His throat is sore and he still isn't eating very well. We're eating a lot of pasta and soup, but I hope he will be able to eat hamburger again.  We were told that at the end of 2 weeks, he would notice an improvement in everything.  I can't wait.  I'm grateful for hockey season so he has something to watch on television.
