Does anyone know what this rash might be? I've had it a little over a month or so. Started out just on underside of left boob, then under the right one. Stayed there forever until the past few days it's spread like wildfire all the way around boobs & down to my pants line. It's extremely itchy, doesn't leak & I haven't changed anything such as soap or medicine or whatnots. The only thing that changed is I had a pretty bad cold for a few days. It started spreading after that but had been there for a while before. I'm thinking it has to be an allergic reaction to something, mainly because it hasn't spread to my baby and she's always on my boob & stomach lol! I don't really want to go to the doc over a rash but it's starting to kind of scare me. I started taking benadryl yesterday but haven't seen a change. I've been rubbing Aquaphor diaper ointment on it since yesterday also. Sorry for the nasty pictures but it's scaring me lol! Thanks!
