I had a pain in my stomach right after doing the barium swallow test. i also was vomiting an hour after the test. is this normal?

Not usually.: Most people do not have discomfort or vomiting after an upper G.I. barium swallow. There are many possibilities as to the cause of this. It could be whatever underlying problem you may have in your digestive tract. It also may be anxiety over the results. I would consult with your doctor who ordered the test once the results are available. Good luck.
