Please call your doc asap. It often took me several days to recover from a colonscopy or barium swallow but your symptoms sound a bit alarming. Stay hydrated, perhaps apply a heating pad, warm bath, shower, drink warm/sweet liquids. Hopefully you don't have a blockage and are not distended. Sending good vibes.
