About three months ago I had gotten some cold water on my shirt while washing the kitchen sink and when I took my shirt off I noticed painful dark red blotches on both of my breasts where the water had hit. I had attributed it to my skin issues with detergent and the possibility that the water had "loosened up" leftover detergent since on one all the redness slowly went away but on the left it generally stays at least a light pink but when irritated it gets darker. I worry that it could be IBC as it is a red rash and I'm waiting on a doctors appointment but since it hasn't gotten worse and there is no swelling is it likely to be IBC? Does an ibc rash mostly fade and then come back sporadically?
