Pimples on my lower stomach?

May need antibiotics: Rashes are hard to describe in words, but pimples usually means raised small bumps with some pus inside. Pimples on a part of the body that doesn't normally get acne, would not be acne. Instead they would likely be caused by more dangerous bacteria such as staph. A doctor can evaluate and start treatment with antibiotic cream and/or oral antibiotics. If not bacterial, a doctor can still help.

Can be anyting : How long duration, do they inch.. Do they bother you? Probably need to be looked at by your primary care provider.
