Quick answers!

I'm having really unbearable chest pains on my left side and my left arm was hurting really badly when I was sitting up. I'm laying down now so the pain is mostly in my chest. I'm only 19 so I don't think a heart attack is possible. I tend to not drink enough water and drink a lot of soda. I also ate hot wings earlier, so I guess it could be acid reflux. But I've had acid reflux terribly all my life and it's never been this bad. It isn't a burning pain. It's a really painful ache and I can't move or it hurts worse. Or breathe deeply. Help me out please. It's so unbearable.
