Re: pain in upper right side of abdomen
Absolutely, this could be gallbladder. Get the test run on it, not just the ultrasound but the ejection percentage test. That will tell you. I was dizzy a lot after eating, had pain in various places, pain in the LEFT shoulder, and had a lot of chest pain with my gallbladder. It never showed up as classic gallbladder pain, but the gallbladder is gone now, along with most of the pain. Good luck.
