I didn't have lots of acid that I was aware of...it always accompanied gastritis, which definitely revved up my reflux. Reflux was the culprit, though.
It sounds like you might be having spasms. Do they start less painful, peak at some point, then subside for a bit?
It's tough waiting for appointments, isn't it?!! If the pain is that bad, by all means call your GP and get some help in the meantime. He/she might be able to provide you with some help.
Good luck! Wish I had more to offer!
