Welcome to OCF, Josee. We are glad you found us, but sorry you had to. I had similar treatments - 7 weeks of radiation and 3 cisplatin. I had a pretty rough time with my treatments and used a PEG tube, which I hated, but was glad that I had it. I was also nauseated a lot, so his reaction is not uncommon. My cancer was on the left side of my tongue, but I was negative for HPV. I also had a weird thing happen with my hearing, but in my case, it was temporary. Make sure that he stays hydrated. That is really important. I had to be admitted to the hospital after I had completed my treatments because I wasn't getting enough nourishment. That was really discouraging. But I am going on three years out, and I am still here! I am sure that you will here from others. Good luck!
