I am a 35 year old woman with recently very sensitive breasts but especially hard nipples. When it's cold, all my life, it would hurt a little if my nipples were cold and hard. However, recently they've been more hard than usual and it takes longer to warm them up. I know it's really hot and I've got my air-conditioning going all day long but this has been ridiculous. My breast, I feel, are sensitive because of my nipples being so hard for extended periods of time. I find no matter when, morning, daytime, evening, I'm always trying to find a sweater or blanket. I know that menstration might have something to do with this but it's never been this bad. Is this because I'm getting older? I know this sounds crazy, but I'm thinking maybe I should be concerned? Interested in your opinion.
