Thanks for the responses everyone.
Babs66, I haven't had a beer in years, and this is a very recent development. The two types of drinks I had last month was a pina colada and hard apple cider.
Stacy01, I mentioned this at a dr. appointment last Thurs. and his thoughts were the same as yours. I have acid reflux and he was inclined to think that was the cause of my discomfort. It's interesting about jaw pain being linked to heart attack pain, I would never have thought that, but it's good to know.
The strange thing is that I began having similar jaw line pain while I was having a soda yesterday afternoon. I'm starting to wonder if it might actually have something to do with my teeth? I'm due for a dentist appointment anyway...bummer.
