I think the experience itself is exhausting. I had a headache after an MRI with contrast and another time, after an MRI with contrast again, I felt ok. I agree with drinking lots of fluids to get the contrast out of your system.
I think the noise plays havoc on an already overstimulated body. The contrast dye shouldn't make a difference but it might have. Something new for your body to deal with. It should be eliminated by the next day. Rest and drink lots of fluids. Hope you feel better soon.
What you went through is a big deal. Being tired seems entirely natural. Sleep well, and you should feel better tomorrow already. Even better the next day.
@A MyMSTeam Member LOL. Actually I thought us being smarter was a given. The analogy I was shooting for was the fact that having MS we have to deal we these rogue antibodies that don't seem to have anything better to do than creating lesions in our brains. But you can spin this however you want.
@A MyMSTeam Member can I assume by more brain activity it really means we are so much smarter? I'm going to fly with this analogy sounds good enough for me
