Hey Mark

I prefer the term "old frack" to nasty dog, but what can you do with youngsters like Donfoo. (George Carlin used to say he was not an "old fart" but an 'old f***" which term you cannot use on OCF, so I went with the Battlestar Galatica version of "frack")

If you do not already have a TSH blood test showing the exact number of your TSH hormone, get one now before radiation. I am shocked by how many doctors do not insist on this, but most went to medical school in the 20 century with little focus on endocrinology. After all the TX, you want the TSH level to be the same as it was before. Without knowing your pre radiation level, you are stuck with a guessing game since the "normal" lab standards run from 0.3 to 5.0, a gap that is meaningless to an individual. Before radiation, back in August 2007, my TSH levels were 1.68. They shot up almost 300% after IMRT to 4.3 and remained high after CyberKnife at 4.2. But all perfectly "normal" according to the lab ranges. I found an endocrinologist who went to medical school in the 21st century who knew it should be no higher than 3 who put me on a pill and now I am back to 1.6. Otherwise you will suffer uneccesarily from fatigue and cold until your TSH is back where it should be.
It's a tough road coming up ahead, but you can do it
