I am 18 for the past 2 years I'm feeling too much warm inside and suddenly the heat increase while doing some physical activity or sometimes without any reason and suddenly I feel itchiness all over my body. It feels like i'm getting stung by bees. It happens several times a day 2 years ago everything was fine. When this problem started I also got acne problems now I get acne all over my body like my face, back, thighs and calves. I treated the acne but after some time again acne problem started I feel this is because of my warm skin. Please help.
