Just a quick point - I think you should have had your c-spine done too as you can have lesions in the spine and not in the brain, and have "cervical" ms - mine was like that initially, and I have always had mri's of both areas at the same time.
I have had ms for 8 years, and only in the last 2 years have I developed lesions in the brain, previously they were all in the spine, with corresponding symptoms (numbness, weakness, spasticty/stiffness, pain - all in the rt arm and leg/hand and foot and L'Hermittes sign) and more recently, fatigue, cognitive issues etc...
Maybe you can have an mri of your c-spine if you feel your problems are all there, then you will have something to show the neuro, without having him send you, then you having to go back to him...I am not sure how it works in your country, but if you can, get your GP to order the c-spine mri and have it done now, before you see the neuro.
All the best - this is good news that your brain is still there and in "good" shape!
Take care and keep us posted.
