What do you suggest if my neurologist told me i have a 'high probability' of having multiple sclerosis?

?meaning: Maybe your testing is consistent with MS, and if so, it requires therapeutic intervention sooner than later. Good oral drugs available, and if aggressive issues, may start with Tysabri (natalizumab). Would add Vit D supplements, and maybe low fat, low salt, diet.

MS probability: If you have a high probability, either your work up is inconclusive or they are unsure. Normally, people who have had an MRI of the brain a c-spine and a spinal tap, with the right clinical history, will either know their diagnosis, or be considered to be in a situation known as clinical isolated syndrome. There must be a better explanation. Perhaps they told you about treatments?
