Huge, sore boobs.

I've always gotten the boob symptom a week before I get my period, but the last couple months it's been starting at my ovulation date and lasting a whole two weeks til AF comes. (It usually stops the first day I get it). But it's SO PAINFUL. They grow SO big, they don't even fit in my bras, I can't walk up or down stairs without holding them. My SO gets mad because I won't let him touch them at all during this time. I'm sure most of you know where I'm coming from, they are just so sore! Sometimes I massage them while laying in bed, but it doesn't really help. Does anyone have any suggestions on how to get at least a LITTLE relief?
