What is CAH?  I’m tormented by sweating profusely only on my head.  It’s caused a lot of hair loss of my formerly thick hair.  I’m postmenopausal but have stopped taking estrogens because of their side effects so I don’t want to start taking them again.  Why would somebody sweat just on their head like I do?  I’m almost suicidal because of it; it’s torturing me.  This started almost two years ago; I’m 61 now. Kindly tell me what CAH is so I can ask my endo dr about it.  Thanks for any information you can give me. ec
