Chest pain

Idk if anyone else experiences this but sometimes when i am laughing or just walking around or not really doing anything my chest will start to hurt and i have to stop what I am doing. When it happens breathing makes the pain worse. Last night I woke up in pain at 3 am crying becuase the pain was so bad and i wouldn't stop no matter what i did. And it felt like something was in my throat. I tried to throw it up, drink water , etc. Nothing worked and i just ended up laying on the floor crying holding my chest. Breathing hurt. Idk what it could be? Any ideas?
