Hi Schuylermommy and Michelle,
Each case is individual, so your doctors are the best ones to decide whether or not what you're experiencing is GERD or something else. I can just tell you my experience. When I would get a GERD flare up, I would experience a burning in my esophagus, and a feeling like a lump kind of behind my breast bone. Also, I would not be able to eat more than a quarter of a cup or so without feeling full, and could only eat the most gentle of foods. (I have a very reactive stomach, which would also be affected.)
If what you have is a GERD reaction, it will take time for your esophagus (and possibly your stomach) to heal. The membranes are very delicate, and take time to get better. It would take me months to get things back to normal. It's important not to eat any GERD triggers (caffeine--and coffee of any kind because it's so acidic, chocolate, peppermint, fried foods, spicy foods, etc.) until you heal.
I do think you should see your docs. Michelle, they would need to do an endoscope to see your stomach/esophagus. I've had that done at the same time as a colonoscopy, so if you're having symptoms like these, you should let your doctor know, so he can decide whether or not to add an endoscopy to your procedures.
If your GERD is sending acid up your esophagus, Schuylersmom, you could get an irritation all the way up to your mouth...Many GERD sufferers have reflux that causes then to taste acid in their mouths.
Good luck to both of you!
