re: I thought I was going to die last night. Wtf is wrong with me

Had the same shite. Many times. Then they found out it was my gall bladder. Here's the coolest part. They removed it, and I still had attacks a few times before they finally stopped happening.

Did you tend to want to be curled up when the pain hit?

*edit*

Also, mine was more center alignment and chest cavity area... feels like someone really strong punching you in the solar plexus where you fold up and lose your air, on top of that extraordinary muscle cramps/seizing up.
