I’ve had these red marks on the lower part of my breast for years. A couple different doctors have seen them but said nothing about it. I have tried everything to get rid of them. Lotions, deodorant, anti Chaving creams, switching laundry detergent, buying more expensive and better fitting bras. Still they won’t go away. Every once in a while I get a couple blackheads in the marks. I was told by someone that it was because my bras were too small but like I said I bought a bunch of new bras that fit better and they have been bothering me again lately. So far the best thing I found that somewhat worked was Aveeno body yogurt. Any tips on what else to do? They burn right now.
