In the scenario that you present a gallbladder source is not likely. A HIDA could be repeated but, if I understand you, the pain came on after trying to come off acid suppression with a long history of reflux. This would be the more likely source.
Also forgot. I had a hida scan done just over 1 year go and it was found to work properly.
Thank you for your answer. Yesterday I began to have upper middle adominal pain. I woke up from my sleep this morning with some pain and not feeling well. The feel the pain radiate in different parts of my stomach from my upper middle, lower right side to my left side.
I have co-workers that have came down with the flu recently but I don't know exactly if this is the flu causing this or related to the pain i recently been having.
Time to get your GI doc's opinion.
