Chest pain after only one drink?

Had my 21st last week, got some alcohol to celebrate. I only drink socially, and even then that’s like once every few months. Decided to have exactly one Twisted Tea a few nights ago, and I got about halfway through before my chest started hurting. The next day, my chest still hurt for about 24 hours and then stopped. All of the online resources I’ve found are for heavy drinkers, which I’ve already mentioned I’m not. I don’t think acid reflux usually lasts that long, and I had a heart condition when I was a baby, so I’m worried it’s got something to do with this. I have a doctor’s appointment scheduled, but does anyone else has any thoughts/similar experiences?
