Hi Minniea, welcome to the HYPO club! I bet if you look back you might see a post or two about fatigue and body temp. as a sign of THYROID problems. My suggestion is that you watch the TSH numbers and make sure they get them below 5. I have come to realize that just 1 or 2 numbers mean he difference between feeling good and normal vs feeling like cr-p. The Synthroid takes a few weeks to take effect so get regular blood tests.

People should realize that the usual "expected" time frame for radiation induced hypothyroidism is around 2 years. I believe it is sooner than that and that the numbers reflect a lag in diagnosis. I felt bad for many needless months before my first thyroid test.

My strong advice to all GET A THYROID TEST BEORE YOU HAVE YOUR FIRST RADIATION TREATMENT.

Then have a test every 3 months after.

Hypothyroidism is a common side effect and results in needless suffering.
