meg92608: It's very possible that this could be fibrocystic breast disease. It's not serious. It's just lumpy breasts. It can be aggravated by caffeine. I've had it for years and now that I'm going through menopause it seems to be quieting down. I always knew when my period was coming because they'd be sore right before. I had to wear a sports bra to help keep the ladies from jiggling too much.
The next time you have a breast exam by your gyno ask him about it.
