The sides of my upper body have been dry for about 4 months. That's besides this new concern. A few days ago these little red bumps started appearing on the left side of my upper body. There's only a couple on the right side. When they first appeared I thought bug bites, then herpes, then sweat dermatitis, maybe eczema, maybe an allergic reaction, don't think it's shingles. Never had chickenpox. They really don't itch. They are dry & rough feeling. I'm 27, somewhat active with safe sex, no problems in genital areas. I'm clueless.
