Thanks Charm...was just signing on to look for your posts and this answers my question. I'm pushing hubby to see an endo. I nagged his GP into going thru records and in 2000 he had a TSH of .67 and was healthy. DX was in 2008. He is now at 3.89 and I have copies of other blood tests showing on average 1.0 increase per year over last 3 years. I believe he was symptomatic at 2.64 (or thereabouts). I'm up to my ears in docs these days (hubby, uncle, mom, 2 grandkids and myself) and have a tendency to question everything. Searched NIH and couldn't find much there on the hot flash thing and that made me even more skeptical. Thanks so much for your input and advice...highly valued as always.
