Welcome, Joyce.

. Good luck with your MRI. I always took Valium before "shooting the tube".
I decided, after my last
MRI, that I would never have another, unless they suspected something other than MS. I figured they are too expensive and unwarrented, after you have been DX....the same for LPs.
After 40+ years with MS, I think I know more than they do..LOL!
Let us know how it goes.
