I don't know if this applies to this specific board but maybe some of you guys can help me out to figure out what's going on and if I should be really worried about it.

About 4 days ago I started having really bad chest pains on the right side of my body. It hurts from my neck to about 2/3s of my stomach. I've been having a hard time breathing and it's like a constant pressure that sometimes gets worse (like a stabbing pain) when I breathe or cough or even really just move.

I've already set up a doctor's appt but I have to wait for another 15 days before they can see me. Should I just wait till my scheduled appt or should I go see an ER Dr?
