Thanks for your replies, finding the site a great source of information.
However today I've noticed symptoms getting worse.
Luckily I'm still able to work (in IT so not physical) and I've noticed that my vision is still blurred. I've just looked at my monitor with my left eye closed and yes everything slightly blurred/ foggy. However upon closing right and and looking at screen with just left eye I noticed that what I could see was shaking left and right very quickly. My up limbs are visibly shaking nearly all the time now. I'm trying to be patient and wait until I've seen the Neurosurgeon on monday (first visit) before seeing GP, but I can't help wondering if they'll give me a diagnosis. I just need to know, whatever it is.
