I have recently started having a dull pain in my chest which only occurs when drinking water (I experimented a little, and I know that's bad). I looked up online and learned that this may be acid reflux, but I have never had a case of this before. I don't think I have acid reflux or GERD, but is this something I should just wait to pass, or is there something that can be done about it? I read that drinking a little vinegar in water will help, but I'd like to hear from a doctor.
