Hi just recently i noticed my left nipple fully erect more than usual and a bit sore. This has been going on for a week. I m 47 years old and this is the first time in my adult life this has happened. I havent had my menstrual cycle since mid Feb. 2014 but i still feel like i get phantom symtoms during the time i wouldve received it. This week would be the time my period visits me. My nipple seems like its a lil darker than my right. Should i be concerned that its more than hormones in my body and possibly change of life?
