demylenating disease of the brain, M.S.?

Symptoms: blurry vision in right eye, eye pressure in both eyes, nausea when moving eyes, nausea when hearing loud noises, hyper sensitive hearing, memory issues, urinary urgency.No fatigue, weakness or balance issues that MS patients get. Mostly cognitive.
I have RA, and my rheumatologist had me take Humira for a year. I started having blurry vision in right eye. My doctor took me off the Humira and states it brings out the symptoms of MS, if I already have it. So, I went to get my first MRI on a 3.0 Tesla Seimens magnet machine-results were "multiple areas of increased signal intensity in the periventricular white matter, consistent with demylenating disease of the brain, most likely MS"
Later I got a second MRI on the same machine with results of "multiple areas of increased signal intensity consistent with vasculopathies and old lacunar infarcts"
Then I got 2 more MRI's a year later on a different machine, a High Field 1.5 Tesla Phillips gyroscan Intera New Technology Magnet. These 2 MRI's came out normal. My spinal tap came out normal. My ENT and audiologist ruled out inner ear issues, and my opthamologist states my eyes are normal. Could this be MS, or something else?
