I have "jackhammer esophagus". I asked my GI doctor about it. He said he had heard a lot of negative results and wasn't comfortable endorsing it or making referrals. Changing my diet, less acidic, gas really helped me. High protein with fiber, green veggies, and lots of warm soups has been life changing. I'm Mexican so really miss salsa. Oh well!!it's so nice to be able to swallow.
