@franduffy I just joined this thread. Your post was 7 years ago, but if you're still in this chat group, how did the surgery go? I was diagnosed with jackhammer and severe GERD a month ago. It has gotten worse alarmingly fast. My question for the moment is what do you eat? It seems like a majority of the GERD-friendly foods are counterproductive for jackhammer. I had bad reactions to calcium channel blockers. For the moment I am just on proton ox and Pepcid to try to help with GERD since it's such a major trigger.
