Hi, Thanks for accepting. I am from the Netherlands. I have CREST since 2012 but not 100% confirmed because I do not have all the symptoms. Lab work shows that and Raynaud's Phenomenon. Also muscle pain and a little dysfunctional oesophagus motility. I respond good with prednisolone. For 3 years I have a rare complaint and I burp a lot. I am avoiding a lot of carbohydrates that are poorly absorbed in the small intestine. A low FODMAP (Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols) diet helps a bit. It is after drink and food, but the whole day long. No reflux. I have an appointment with the GI specialist in May and before in 2015 they found nothing. The oesophagus dismobility was nothing I hope for an answer or feedback, so I can ask the doctor.
