Big booby issues :/

Dina
This is just a random question to all my fellow big chested women out there... (Or maybe this happens to everyone??) 
If im laying down for an amount of time and go to sit up, i get this indescribable pain through my boobs... I literally have to hold them and like compress them to get the pin to stop... 
It's not just when im on my period either, it feels like my boobs weigh an extra 10lbs.. Its almost like a burning sensation, kinda as if the blood was rushing to them??? 
Does anyone else get this, and why the hell do my titties betray me like this?! 😂
