Breast question!

Maranda

One of my boobs feels so irritated like I have a rash. When I itch it there is absolutely NO relief. I cant find the exact location of the itch and think it may be inside. I am also exclusively breastfeeding my 4 week old and when her nails tickle the area it is SUPER irritating. It does not hurt at all, just is INCREDIBLY ITCHY !!

Does anyone else have this issue !?
