I recently went to the hospital and received a chest xray because of my asthma. They did an xray immediately and sat me back down in the waiting room. after a while I began itching on the side of my right breast. I thought I had been bit my a mosquito or something. but it itched worse than a mosquito bite. a few hours later when I saw the doctor see looked and did not see a bite or anything but it continued to itch. Over the course of a week and a half, spots that look like small burns have come up and the itching remains but not as bad. it spread over the side and front of my breast in about 10 spots. I figured I had been bitten by a spider or something. but the spots get larger to the size of a pencil eraser. now I have three more itchy bumps come up. what could this be?
