About a week ago I noticed a small opening in the skin right inside my labia majora (almost at the edge). At first I thought that I probably nicked it while shaving, because I noticed it a few hours after I shaved. I've been putting antibacterial ointment on it, but it does not seem to go away. It's not bleeding, but it's red (exposed skin), it hurts when I urinate and wipe, it hurts when I wash with soap. The pain (pulsing) usually lingers for a while and then goes away. I forget about it until I urinate again. It's not getting any bigger, but it does not seem to go away. I also considered the possibility of an ingrown hair, but I don't see any hairs in the open sore. I'm freaking out thinking that it might be herpes... Does anybody have advice for me? I would really appreciate it. Thanks!!!
