It has been a month since I had a mammogram, and a repeat mammogram on the right side. A few days after the mammogram, I started to feel a tingling sensation in my nipples, mostly on the right side and only occasionally on the left. After a week or 2 of the tingling sensations, my breasts are itchy , especially the nipple area. And again, mostly on the right side. Could this tingling, and now itching be from the radiation of the mammogram? Or something more serious? There is no change in the skin's appearance.
