1 pointWilliam, sorry your symptoms have gotten worse. I had a nasah in 2012. I had similar symptoms except fot the gait. My double vision corrected itself quickly. I had trouble with my words as well. I still do sometimes if I’ve over done things. Do your symptoms seem worse. When you are tired? I’ve learned if I fail to hydrate well and try to push through ,when I know it’s time for rest, I pay a price!
