Yesterday I went to the US and had two MRI's done. Brain, with contrast, and cervical spine. After cervical spine and the first brain scan they did the contrast. First of all, I thought I peed my pants. I didn't but it sure felt like it. I have since read that this is not an abnormal feeling for people getting contrast for scans. However, my tongue also got really hot and felt like it was swelling up. I thought I was having some weird kind of allergic reaction and my tongue would block my airway. Nothing happened of course. I almost freaked out but we were almost done (the whole thing took 2 hours). I knew it was going to cause major PEM (which hasn't kicked in yet luckily), so I wanted to make sure it all got done and I didn't have to do it over again. Anyone have this happen before with an MRI?
