Katrina,
Are you taking Dapsone, and are you allergic to sulfa based drugs. I do, and I am. There pharmasist told me that the pimple like bumps are an alergic reaction to the sulfa in the Dapsone. I have them mostly on my stomach area, and mostly on the left side of my stomach. But for what the Dapsone does for my Mechanic's Hands, I will put up with it.
