Some people have silent reflux, which means that even though they do have it, they do not experience any symptoms such as heart burn, belching, regurgitation, but the damage still occurs.
There is a small percentage of people, including myself who experience reflux in the larynx/ pharynx instead of in the esophagus. The mechanic is to known. People with my type of reflux are unfortunately the unlucky ones, because it doesn't respond very well to medications or the operation.
My symptoms before the operation were the same ones that I am experiencing now, severe sore throat, belching regurgitation, inability to talk and hoarseness in the voice.
What have you heard about the Nissen Fundoplication? How long have you had reflux. I have for many years. If yours is intractable I wouldn't wait to long and I would take my chance and have the LINX implanted. Where do you live, in the States or in Europe?
As far as I know, there is no relation between Ibs and reflux. What is your natural approach. I tried everything but nothing worked with me, including ago puncture. I hope you are going to be more successful then I ever was.
