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.
