It started about 2 1/2 years ago... Every time I walk, exercise, ride a bike or anything of the sorts (and sometimes I can just be sitting on my couch) my body temperature feels as if it rises and I start to sweat profusely within 5 minutes. It is always to an extreme...the other day it was -5 outside and I walked 5 blocks, by the time I was half way to my destination I had to remove my hat and scarf because I was sweating and felt so hot. As an example, my 200 lb husband will be bundled up because its so cold outside and I'll be so hot to the point that i'll be down to a t-shirt and jeans. I have been to two doctors....I am not diabetic and do not have any thyroid issues, which were the first two things they checked. I am not overweight either. It has recently started to get way worse...if I drink anything hot, eat anything hot (temperature hot, not spicy), blow dry my hair, etc. I start to sweat. I did an experiment for a week, I rode my bike to and from work, when I got home I would stop outside and take my temperature, it was 94 degrees, after 10-15 minutes of cooling off my body temperature rose back up to its normal 98 degrees. They want to send me to a neurologist, but I am hesitant as the first two doctors just blew me off saying that "everyone has different reactions to exercise and temperature". I am desperate. It is at the point that it has started to embarrass me, if anyone has any ideas they would be most appreciated!
