Hi AGS I get silent reflux (I don't get acid in my mouth and can't feel the burn in my oesophagus until the damage is done and I get severe oesophagitus). My pains started in my abdomen a year ago and they nearly whipped my appendix out! I have had all the tests and everything is normal, except anaemia and malabsorption of food.   It's trial and error with the foods. You have to really tune into your digestive system to see what improves/hinders your condition. I have become a bit of a food and drink purist, but it has helped enormously (unprocessed, unrefined, natural, non-acidic, non-spicy foods, herbal teas, easy on the gluten, no alcohol, no coffee etc).   I am still a mystery to the docs and will be seeing a gastro specialist again soon. There is a possibility that mild food intolerances ignored for years may have led to inflammation and thus reflux, IBS symptoms etc. Perhaps you are the same??   I run 10km a couple of times a week now and don't get any burps or pains afterwards. Apparently running is something we are not supposed to do as it increases reflux. Before I started running, my endoscopy confirmed my LES muscle was fine but my oesophagus was swollen with damage from acid. Now the inflammation has gone and I run, loads, without problem... figure that one out.   Sometimes, we just don't fit into the textbook for symptoms. I have swore blind to every doctor and consultant that I don't get indigestion. They just look at me as if I am making it up - because my damaged oesophagus was telling them something different!   Listen to the advice of the doctors - but don't forget to listen to your "gut instinct"!   Hope this helps Suze
