Re: Night sweats and pimples
I had nght sweats a couple of years back - now I'm 50 and I don't seem to get them, but I get more of a warmth/flush during the daytime.
I also had a period of time getting pimples on my breasts. I think your right about the sweating aggravating it, and the skin being more sensitive/thinner there. I found the best thing to do, is leave them alone - no squeezing or popping - this will reduce scarring - although it may not completly eliminate it.
My dermatologist told me that I have the type of skin that easily scars, so that may be your issue also.
