Hi. I have a pustule in my groin area. It started from an ingrown hair, which I plucked, and it got infected. It grew in size over the next few days without me noticing too much, and here I look and I've got a pustule about the size of half a dime on the side of my ballsack between my left leg and my testicles. I put peroxide on it a few times to try to clean it out, but I'm not sure if I'm helping it or hurting it. Should I see a doctor or does anyone have any info that might help?
