Okay, so I've had some spells lately where it feels like something is constricting my chest or neck and it feels like I can't breathe or like my circulation is somehow getting cut off, even after I take my bra off. Only two things have changed for me recently since I started having these spells, I've gained 13 or so pounds which has caused my breasts to grow a size or two larger (as well as my belly), and I've started taking my old ADD medicine again. Normally I would suspect the medicine, but I've had this prescription for awhile now and it's never affected me like this before. I was wondering if there are any women whose had breathing difficulties because of their breasts weighing down their chest? I'm currently a size 38D (C with some brands). I know it seems silly, but it really feels like this might be the reason and I just want to know I'm not crazy.
