Hi, this has happened to me within the past 10 years, and it only happens during seasons with cold weather. When I get hot, or nervous, or anxious, where normal people are described as breaking out in a sweat, I get excrutiating pain all over my body. It feels like i am being stabbed by millions of needles, I itch, and my skin turns bright red. Once I actually start sweating, and there is actual persperation, the pain goes away. Even if I am swimming and start to "sweat" the pain comes. My father, a doctor, thought it was a sort of allergy and gave me Atarax, I think that was it, but it didn't help. During the summers, the pain doesn't come. If I were to describe what I think is happening, it's as if my pores are sealed and when I need to sweat, they don't open unless I start sweating profusely. Is there anything I can do for this, or what is this? Thanks for any helpful answers.
