I had this done on Tuesday. The actual scan itself wasn't that bad. The radiographers and nurses were lovely.
The big issue for me was the prep before. You have swallow gastrografin a couple of days before hand, and eat a roughage free diet.
Gastrografin is the worst tasting liquid I have ever had to drink. It's like drinking nuclear waste! It's an iodine olution. This combined with not being able its eat before the tests on the day triggered an almighty migraine.
I had two buses to catch in order to get to hospital. I managed to just get off first bus before throwing up spectacularly right in front of a crowd of people. They must have thought I was an old soak!
Onto second bus with head banging and stomach doing somersaults. Then a lady sat next to me wearing the most over powering perfume ever. If you've ever suffered a migraine you will know my misery and pain.
Finally made it to the hospital, only to be informed that I would have to drink another jug full of weaker contrast.I was nearly sick on the spot! How I managed to stomach it I don't know, but I could feel it churning dangerously in my stomach.
Thankfully the scan itself only took twenty minutes. The lovely nurses dimmed the lights for my poor head.it was a bit like being in an alien space ship with the blue flashing lights, whirring....and anal probe!
You've got to laugh.
