I am sure someone on this wonderful board can help me again-- I suspect that I have GERD, have acid reflux and belching that is getting worse and not really helped by OTC medications, but I have to wait a couple of months for a GI appt. Anyway, today I experienced something different and very, very unpleasant. I had just eaten a small piece of cheese and a couple of dried banana chips, and all of a sudden, I experienced a horrible wave of nausea and then something very vile tasting and acidic come up into my throat! It was different than the usual acid reflux stuff. After that, the nausea went away as quickly as it came on. Could this be GERD or might it be a gall bladder problem? Thank you!
