Is this normal

F

So I've been wearing a sports bra lately, I was being stabbed in the boob by an underwire, don't judge. Anyway, I just went to torrid and got myself 2 great bras that fit perfectly. But I still experience back neck and shoulder pain because I am a bit busty, I'm at a 38D and I can't handle it, it hurts like hell and exercise is awful. Is this a normal size to experience pain with?
