I had the TIF Transoral incisionless fundiplcation. And I too am in
pain and have as much if not more heartburn/
stomach pain than before. The first few months I was fine, but not any more. I don't recommend the surgery - I did at first. Am going to see my Gastroenterologist after the holidays. The surgeon only said, "Well. I can't do any more to help you."
Sometimes fennel seems to help the pain or anise. But for the most part, I hurt after I eat.
