Breast/nipples irritation

So pretty much I went to the doctor and she told me as I got old my nipples would start clogging from breast milk developing, even though I am not and have no been pregnant. She told me to take a wash cloth while I was in the shower and then start lightly rubbing my nipples and then get rougher to clean them.  Pretty much I can wear a bra now because they hurt so bad and burn if I try to but lotion on them to help with with irration. Please no rude comment       But what would you suggest to help the irration and soreness?
