I too have severe GERD, diagnosed with an upper endoscopy. If I bend over, I feel burning and sometimes the reflux reaches my throat. I am on Nexium 40mg, tums too on occassion. Awhile back, the docs were considering a procedure called Nissen fundoplication but scratched that once my respiratory status went to hell. I suspected reflux when tasted acid in my mouth, believe it or not, I didn't get alot of heartburn. Many meds also aggrevate mine...so many of the antibiotics do, especially the cyclines such as Minocycline and doxy as well as Zosyn. That one is TERRIBLE! Of course the NSAID's will chew you up too if you have reflux. I too hope that you find relief and answers...hugs, Jenn
