Cyst or infection: Probably either an epidermal cyst that has ruptured and become inflamed/infected, or a plugged oil gland that has become infected. These are common around the waistline, which is warm and damp and continually irritated by clothing. Your doctor or a dermatologist may need to drain it and prescribe an antibiotic.
