Hi Burnin'Up,So sorry you're having so many problems. Unfortunately, I don't have any ideas that might be helpful, but I would suggest that you find a surgeon who deals with redos on a regular basis. Redos are a lot different than original Nissens, and you'll want to find the best possible surgeon for the job.
Do you live near a large medical center? I suggest you do lots of research, interview a couple surgeons, and then decide what you want to do. If your original surgeon doesn't have a lot of redo experience, I recommend you look elsewhere for the fix.
Wish I could give you more help!
Best wishes,
Denise
