What Causes a Rash on the Breast?

Does anybody know what these are? They hurt when touched and I didn't even realise I had them until earlier today. Is this serious? : r/bigboobproblems

Weird rash appeared under my left breast. Skin around the area seems sensitive, but isn't red. Feel the same on my back too, but no rash there. Any idea what it is??
