Thi is kind of embarrasing but I have had excessive sweating underarms mainly ,since puberty and I'm 21.?

Are there any solutions? I've tried using different clinical deodorants or no deodorant at all and I have to layer my shirts. My face will get flushed every day at least once and I will sweat immensely. It feels like what I would guess a hot flash would feel like. I have asked my dermatologists but he says its just hormones and suggested I use an electrode device that is supposed to send an electric current to stop the sweating temporarily. I have heard that this is painful. I want to avoid sweat gland surgery if at all possible. It can be freezing outside and I will sweat and during the summer, I sweat everywhere. This may be too much information but I am desperate for relief. It makes me very self conscious especially when huggin some one. Thank you.
