hello, my dad had his salvage surgery 6months ago, and completed his radiation and chemo about a year ago. these last 6weeks he has been very fatigue.. his thyroid med (synthroid) was increased about 4weeks ago but his energy level just does not seem to have gotten any better.. he is also on the 50fent patch and takes a norco about every 4-6hrs.. we have an appt tomorrow with his ENT surgeon and med oncologist.. he seemed to be doing a lot better after the surgery then now.. he is never out of bed anymore.. i understand his body and mind has been through so much.. hoping to get more answers tomorrow.. any suggestions would be greatly appreciated. thanks so much
