Does anybody know how to get rid of underarm sores? When I was smaller I used to shave my armpits with an electric razor because that was the way my mom does it and I just followed her example. It used to tear up my armpits because it was too harsh. I haven't used an electric razor in years but now I have 2 lines of tiny sores that go under both armpits of mine that have been there for years. They don't hurt or anything, but they are just annoying because I always feel self-concious wearing sleeveless shirts. Does anyone have any suggestions on how to reduce them or at least make them less noticeable?
