I have a question about a problem with my breast. About 2 weeks before Christmas I got a rash on the underside of my left breast that was more like a burn. It was very hot and my whole breast hurt. It started out the size of a nickel and soon covered the whole underside of my breast. The only thing that gave me any relief was a cool wet cloth. After a few days it faded to a brownish looking area that rather looks bruised. My breast still itched and hurt. Eventually the pain spread to under my left armpit. The spot sometimes turns bright and sometimes I get a line like I wore too tight a bra under that breast whether I wore a bra or not. Last night I noticed my breast has swollen almost a full cupsize and my nipple started hurting. What could it be? Should I make an appt. with a doctor and if so what kind? Thanks
