I have a lot of belching/burping & often - but not always - with pain i the upper middle back - between shoulder blades & somtimes around my the top of my roght shoulder. pressure around the bottom front of my ribs.i have sjogren's syndrome?

Possibilities include gas entrapment in the esophagus, GERD,esophageal motility disorder,or gallbladder pathology. To prevent gas, avoid gassy foods&gassy beverages and take simethicone 1/2 hour after meals. Try not to make yourself belch excessively. If not improved,I recommend consulting a gastroenterologist for evaluation,appropriate testing and advice.
