I am 51 years old, and have become intolerant of heat. I perspire very easily, but mostly in the coccyx area. I will literally become dripping wet, looking as though I've wet my pants, which as you can imagine is extremely uncomfortable and embarrassing. I am 130 pounds, 5'5", have been dealing with a strange fatigue and pain in my upper abdomen that radiates to my back. I am also chronically thirsty.
