Hi, Sellfly, its ok, to be nervous( anyone would be) I've been there twice, the first brain MRI the neurologist was looking for CMT( carpal tooth syndrome) lupus & because my mother had Alzheimer's he was checking for that, & also, set me up for genetic testing for the Alzheimer's, so Shellfly, Nervous became my middle name, lol! The second one was done this past January also without contrast and that it's the one that resulted and the diagnosis of MS, the diagnosis gave me relief, because for so long I've had various aches and pains, and prior to having multiple sclerosis I've had my foot drop, it felt so strange,because mentally I could not move my foot! I found myself sitting down for almost 2 hours before that sensation left, and I'll tell you I was very worried my thought went to I must have some sort of brain tumor,ect. Shellfly, I don't know if this suggestion will help you, but tomorrow, just remember that at least you'll. be on the way to having some answers & from there you'll be able to start planning what needs to be done next☺. Shellfly, l wish you well, and; please remember: Facts Over Fear ! (F.O.F)
