I am a 60 yr. old woman who is suffering with extreme sweating, (all over, soaking wet) that then goes to freezing. I can be in the coldest room and be in a full on boil within seconds followed by getting cold and clammy. If I try to warm up, I break out into another round of the same. It has been going on for yrs. now. I literally wear a fan around my neck and have fans everywhere in my house. Other symptoms: headaches, weird rashes, trigeminal neuralgia, thinning hair on scalp and no body hair. This has been going on for years, long before menopause and after. My thyroid test (fasting) was ok. I am so frustrated and it affects my daily existence. Please help if you know anything, pls.
