Good luck with the MRI, I hope it shows nothing.
Can't say I have no symptoms, but my neurologist keeps calling my MS benign because I haven't accrued disability. There are better and worse forms of MS. And it can take awhile to get a diagnosis. I also had no banding in my spinal tap. I had a lot of anxiety back when I had three kids under five, and it was at least indirectly MS related because the demands on me were so great and I spent every day well past my limits. It helped to cut back.
