Nicki,
Hair follicles lost to radiation don't grow back. Like Brian, I could grow a goatee, but the part of my beard on my lower jaws will never grow back. (not that I mind...it leaves less area to shave, and the skin is as smooth as a baby's).
It took a while, but even with my limited diet, I have gained back as much weight as I want...the waist in some of my pants has gotten tight. I feel like I am strong and still play a lot of golf, and can hit the ball as far as I ever could...subject only to my less than perfect golf swing!
Yes, the boredom is one of the worst things about the recovery period after radiation treatment ends. I read a lot, took a daily walk, napped a lot, and even got to where I liked the rap music T.V. shows that came on in the afternoon that my teen-aged son turned me on to. Go figure.
Anyway, things will no doubt improve for Tom, and for you as well in time. The good news is that interest in intimacy returns as well.
Take care,
Danny G.
