I had a painful left breast for a few days. Today it's really really tender and my nipple has swollen and is red around it. It reminds me of when I was breast feeding (5 years ago now so not that) and he'd missed a feed that full feeling. I have Dr's next Thursday anyway for something else. Do you think I need a more urgent one or will it be fine? Also what is it? Google says I have cancer but I know it says that for most things..
