@bananamilk That's scary! I personally would give them a call and let them know what was going on. To me, it sounds like it could be a heart issue, but I'm no doctor. It can't hurt to give them a call and tell them your symptoms. Better safe than sorry afterall. I remember a while back I had some really bad kidney stones. I let it be for nearly a few days, not know it was a kidney stone. I am a stubborn person and don't like to go to the doctors, but eventually the pain became so unbearable, I had to go. Found out I had a pretty big stone, and had to have surgery.
But seriously, if you're having chest pain, it's worth getting a hold of them just in case. Even if you're feeling better, there could be an underlying issue and it could possibly come back.
