Some people that have say Gall bladder problems, have what they call deferred pain and they have pain in there shoulder area, so I could see them ordering a Cholecystography it is a test, actually a scan to check for Gall stones and gall bladder function. I know I went to the doc last year I was having trouble with lots of nausea and vomiting and bad shoulder pain, the doc pressed on my upper right quadrant of my abdomen and asked if it hurt, I said NO, but that sure made my shoulder hurt like crazy, a couple of days later they ran that test, and I had my Gallbadder removed the following week. So may I ask are you sure your doctor said Colonoscopy? and not Cholecystography? For quite a few people with abdominal problems, gall bladder, stomach, liver, they have deferrred pain, and it is usually in the shoulder area. Even some people that have heart attacks don't feel pain in their chest but rather in their, back and neck and arms,. So maybe......
Good Luck to You
