I have the same problem for a while now though somehow it doesn't happened in summer! My local dermatologist describs these pills -in the pic down- for a month and surprisingly it worked! YAY, not for too long tho it actually screwed my immune system really badly, I got really sick from influenza. Also the antihistamines made palpitation especially in bed time... I guess this condition has something to do with dry skin and weird immune system respond to the sweat!! Any way am trying to embrace for what it worth
