Thanks for the well-wishes!
The powder I drank was a contrast thing, and man, it did NOT agree with me. Other than that, nothing too awful other than that darned IV.
No results yet, of course, and I'm keeping my fingers crossed that it's nothing.
So now I've had an US, and a CT Scan....I'm reasonably certain the next is a colonoscopy. Oh, the fun lives we lead with digestion issues.
