Hello, @nolano, and welcome to Mayo Clinic Connect. That sounds quite uncomfortable, and I'd want to figure it out, too.

Here is some Mayo Clinic information about breast pain in general https://www.mayoclinic.org/diseases-conditions/breast-pain/diagnosis-treatment/drc-20350426

Hoping that members here like @trixie1313 @oldertoo @jkhambati @beverly0223 may have some thoughts for you on why this may be happening and next steps. I'd also like you to meet @baxtersmom.

When did your nipple soreness start? Is it constant or is it off and on?

I am experiencing nipple soreness as well. It started about 3 months ago. I’m 57, 4 years post menopause, complete hysterectomy 1 year ago, normal mammograms every six months, dense breasts, normal breast ultrasound, and normal breast MRI about 6 months ago. Went to see my breast surgeon and nothing abnormal found on breast exam. I was advised to continue with monthly self-breast exams, routine mammograms and yearly MRIs due to high risk for developing breast cancer.
