Hi- can anyone help please? I have Raynaud's; have just been put on Omeprazole capsules for the burning sensation that I get in my upper abdomen/under my bust line. (Mentioned previously on this site) Have had the endoscopy which showed no acid reflux. Am waiting for an "Oesophagal Manometry" to test the pressure. (Tube up nose & down throat) For about a week now, I have had a feeling that I am going to be sick; it just comes, then goes again as quickly as it came. It's not related to the Omeprazole as I have only just started them in the last couple of days. Any advise would be helpful.
