Flaking nipples? Help

Okay so this is so gross to talk about but I’ve notice that my nipples are very sore lately and the skin around my nipples are falling and coming off then leaving them very red and sore to touch and end up healing onto my bra which then I have to peel off which makes it worse. Also my right nipple is darker than my left,I don’t know what’s going on and I don’t know what to do. Has anyone got any suggestions?🤦🏽‍♀️
