I always get pain in my left breast in the week before my period. I have been breastfeeding for 2.6 years now never thought i would but ds doesn't want to stop. He feeds three times a day for about ten minutes. my left breast has been getting increasingly tender all the time. I have had mild mastitis before and with hot baths i've managed to massage it away. this pain is behind my nipple. I have lumpy breasts and it is hard to feel a specific lump. Have asked the doc to refer me to breast clinic but just wondering if anybody had had anything similar. Rather worried at mo.
