diddier, I wish I had the answer to make your mom feel great and give you a much deserved break. However, I can only say that after mouth surgery and neck dissection, I had a pretty good blast of IMRT, with chemo, and had no nerve damage. This is the first I have heard of that being a side effect of IMRT, and I did quite a bit of research before I had it. As far as the meds go, I think you are right to be concerned. I think a review of all her medications by her primary physician is in order, or as recommended above, by the pharmacist. I had to do that for my mom when I was taking care of her. She felt better on less medication after I demanded that something be done. Sure wish I could help you both!
