Welcome Rich, Dang
HPV go me too. Radiation is the cure, and causes of most of the problems. Chemo improves success rate 15%ish. If you had two hot nodes, plan on chemo. Most likly cisplatin. There a whole list of things you have to do to get ready. Others will be along with tips and advice. My favorite one is go ahead and eat now and often. An extra lbs or two won't hurt you. Next is dentist. Your teeth have to be looked at very closely. You have to have everything in good shape before you start. Have floride trays made. And start using them. This cancer is cureable, so don't let the treatment damage your choppers.
Also post often, the good, bad, thought, and issues. I bet someone here has been there and the more they know about your situation, the better the advice. Treatment is brutal but doable. I am just under a year out and do well. Good luck and I see you on the boards.
