I had a CT yesterday -- chest, abdomen, pelvic -- 1-year follow-up from the Prochymal study. Three tries for the IV (OUCH, it was through the bruises the nurses gave me 5 days prior when they took 4 pokes for 2 vials of blood! my veins need a rest!)
The contrast dye stung for me when it first went into the vein. I had forgotten that part from previous CTs but after I remembered that I feel the sting each time. It does not seem to last for me, though. (Thankfully!) It stings alright, so I can imagine if it lasted any amount of time wanting to scream! ICK!
Oh - I had about 24 oz of blueberry barium. I was thrilled not to throw up! ;-)
Hope your test shows good things!
