Had anyone experienced a small breast rash? Under my boob there is a slight bump almost looks like a scar. I thought it was just die to my bra digging in or something so at first I completely ignored it. But I would go to sleep with nothing on and wake up and it was still there looks very similar to a scar like how they are slightly raised. Only on one breast. I sent it to my sister to look at and she thought it was from sweating but I shower all the time and make sure it stays dry. I've had it for about 3 weeks now and its not getting worse or better. It doesn't itch or anything. .. does anyone have any ideas? I called my dr and she didn't have any that that work with my work schedule so I'm just going to wait until my next apt as my job is very strict about missing time.
