Betty,

Have you had your thyroid function checked? Even after my daily bouts of post-tx fatigue seemed to go away (about 2 months for me), I would occasionally have a day here and there where I would feel as tired as I did the day after treatment. However, since they were infrequent, I didn't think much about it. Finally, my wife said "you seem much more tired" than you have for a while. I mentioned this to my ENT on my next visit. He suggested having a blood lab done to test for my level of thyroid function as reduced function was a common side effect of H&N radiation. Sure enough, my function WAS diminished, I was placed on a synthetic hormone, synthroid, which I take via a tiny pill every morning. That was over 2 years ago and I've been fine ever since. If I get tired now, I realize it's more likely that I'm 53 and probably overdid it!

It will get better.
