Ob-Gyn questions? Ask a gynecologist online.
Hello, I'm Dr Manos, board certified obgyn. What you describe is confusing. The first thing would be possible herpes lesion but lasting a week seems excessive but painful would be consistent. Feeling pea-sized lump is not consistent. I might suggest getting bacitracin ointment over-the-counter to apply to help healing. Seeing your doctor soon will determine what's the problem.
