It sounds like you could be suffering from GERD. Your doctor should send you to a Gastroenterologist for a 24 hour motility test to see how the acid is affecting you. There are other drugs you can try such as Nexium,, but if the LES is loose, then only surgery is going to correct the problem permanently.
I had a Nissen Fundoplication done in June of 2003. In addition to losing 50lbs, I haven't had problems with acid reflux ever again. I had a very slow recovery due to some other health issues I have, but it was the best thing I've done. I had all the same pains and discomfort you've described and it all went away after surgery
Talk to your doctor about further testing for GERD and good luck with results and treatments. I hope you feel better fast!
