hi! over the last few weeks i've noticed some horizontal red or purple sort of lines across my right breast. I had a lot of pain about two months ago in my left breast and arm with shooting pains which was put down to nerve damage, and it was then I first noticed these marks. They quickly faded and over the last two weeks they have come back a lot darker. At first I thought it could be stretch marks, but it doesn't look like what they would typically look like. There is no pain or discomfort at all, I only notice really in the shower or getting dressed when I see them in the mirror. I'm 21, no children so its not related to breast feeding - does anyone have any idea?
thank you in advance
