I've seen several messages from people on this board regarding night sweats. I have been having problems with night sweats and hot flashes for several years, including when I was on hormone replacement therapy. (I've stopped the HRT, as I had been on it for too long. Instead, I've been taking a combination of black cohosh and soy, but now I'm reading that these are bad for me, too!) But back to the point. Sometimes my hot flashes seem to alternate with periods when I feel cold--not exactly chills, but I feel cold when my husband feels warm (or vice versa). When I saw my new neurologist last Friday, he ordered blood tests, including one for thyroid function. He said that thyroid irregularities might account for the temperature regualation problems. I know several people have commented on having thyroid problems. Has that ever taken the form of hot flashes and/or cold spells? If so, did a thyroid supplement help? Also, if you know, what thyroid test indicated the abnormality? (I had the blood test today, but I don't know exactly which thyroid test--or tests--was ordered.) Thanks in advance for any guidance you can offer. --Laura R.M.
