Victor,
Sounds very similar to my treatment. Stage 4 Head and Neck in December. Only difference was I got the right radial neck dissection surgery and then the radiation. Almost done-just some booster radiation to get through. It's been a tough haul, but better days are ahead for both of us.
My advocate is 3.5 years past his head and neck cancer with no complications. My business partner has a neighbor that is across the street from him and he is 1 year past head and neck cancer and is gaining weight, walking the dog and getting out and driving.
Head and neck is treatable and beatable. It is one of the harshest treatments in my experience, but there is no other way at this point in medicine to deal with it.
You will get through it! Stay posted on these forums for great advice and shared stories.
