Do your boobs get sore like this? (Asymmetrical breasts)

I’m 5+5 and my boobs have just recently got a little sore. But, one of my breasts is significantly larger than the other (always has been). The bigger breast has a sort of lump in it (an innocent lump) but that particular spot is where it’s mostly sore. It’s towards the outside. In comparison, the smaller breast barely is sore at all. I want to say that also happened with my DS but I can’t remember. Is this normal? Anyone else have a situation like that?
