Don't bother listening to so many others. Waiting for my MRIs results I was convinced it was a brain tumor. The years proceeding my DX, doctors and others said they didn't know what it was, but it wasn't MS. My PCP unhappily sent me to a Neurolgical Opthalmologist who looked so serious at me, said he had no idea, could not help me but he could do magic tricks for me and did. (I was cute back then and a captive audience for that frustrated magician-wanna-be.). My PCP then sent me to a neurologist and made me promise her after that I'd stop looking for answers. He DXed MS. No numbness or tingling, I walked funny and always had to pee. My LP and MRI were classic MS. I'm PPMS and firmly convinced in my DX. 10 years after DX I am in a wheelchair but never spasm or tingle or have numbness. I have found many doctors and others in medical community are very unfamiliar with MS and not worthy of listening to. My D and B levels show fine. Everyone's MS or ? is different.
