4 Years Ago, I Experienced About 1 Month Of Blurred

4 years ago, I experienced about 1 month of blurred vision. The onset was very sudden. I went to 3 eye doctors (the 3rd being an eye specialist) and all results were negative. The doctor suggested that I need eye glasses and sent me on my way. Within the matter of 1 month, my blurred vision corrected and have yet (4 years later) use glasses and have had no other visions issues since this time. Here recently (the last year) I have experienced rather odd symptoms. I drop things very easy. I can't seem to keep a grip on small items and my grip strength on heavier items has weakened. I have had unexplained electrical shocks that feel like electricity popping out of my finger type at times. Because I felt (IN GENERAL) poorly, my PCP ran numerous tests: positive ANA, a speckled titer of 1:160; and a high C-reactive protein (just to name a few). I saw a rheumatologist and he cleared me of lupus and sjogren's. I am not trying to back into a multiple sclerosis DX, but is it possible that these ongoing symptoms could point to MS?
