I no this sounds silly, but its been bugging the hell out of me the past few days. when I get an itch in an area like this, I don't scratch to prevent spreading the infection, but I cant help it! it started in my left side and now its on my right side. I haven't changed my detergent or anything or sexual activity, but the last time I had sex (just over a week ago), it started. my left nipple (which he was you know, having fun with mainly) was hurting and sore for a few days after we had sex, which is normal for me, I sometimes will even bleed from my nipple after that, but I didn't, it was just sore. but once that eased up, my nipple started itching. theres no bumps or hairs around it, no scratches or anything like that. and its just the nipple, not the actual breast. I thought at first it was just from it rubbing against my bra, but even when im not wearing clothes like when im in bed or in the shower, it still itches. and scratching it doesn't make it stop either!!! what could it be??? I honestly thought I was pregnant last week, bc ive had some odd symptoms lately and my periods late, but I took a test and it came back negaitive.
