Yup. Strangely, it's my left. My right has always been bigger so I would think, now that it's more obviously bigger, it would be the one that hurts. But maybe my left hurts because I sleep on my left side and smash it or something.
Mines left too and I also sleep that side! Although it hurts to lie on. Funnily enough it's the inside of my boob at bottom that hurts more than other parts x
I'm going to have to start wearing a bra at night. I find that, when I get up and the boobs shift, that's when it REALLY hurts.
