Hi Kadi and Welcome to the group. Sorry if you have to be here, but it's a great place with caring friends who are always willing to share their experiences. I've had a few MRI's which I've always thought feel like you're inside an old video game with all the banging and strange noises. The lesions found with the MRI's were enough to diagnose MS in 1990, so I never had a LP.
Hope you'll stick around and please let us know how you make out. We're here if you need us!
