I subscribe totally the words by @agate, I think you need a brain MRI looking for demyelinating lesions, but, even if lesions are found, the next step would be doing a lumbar puncture (spinal tap) to dismiss other diseases.

MS can have a lot of different symptoms, but a lot of diseases can have symtomps that resemble MS.
I was dx with MS last year, and have been on Tecfidera 1 year so far, no new lesions and no activity on the last MRI, so I'm doing good.

Good luck with your dx, we're here to help!
