Hi, there have been really recent posts about the Nissen procedure and recovery on the Acid Reflux/GERD board. Actually, there was a post involving two different members who had the surgery within the last week or two. I think they both talked about experiencing gas pains in their shoulders and necks. One is really quick to reply. I posted a thread just today and she's already responded twice. The thread I'm specifically referring to is titled something about the Nissen procedure and problems eating. Can remember the specific description. You might try there
Good luck in your recovery. I'd really like to hear your experience and the diagnoses that resulted in you getting the surgery.
