You may want to ask you gynocologist about it next visit. My breasts were very sore and tender, just my bf touching them would send me into tears. I found out during a breast exam with my gyno that I had a tendency to develop fibrocystic cysts in my breast and it got worse before and during my period. my hormone dosage in my birth control was too high and it was setting them off.

Cutting down my caffiene and sugar intake helped A LOT, and so did switching from eating a lot of beef and red meat to a lot more lean white meat, like turkey, chicken, and fish.
