I know, I should ask my GP, but just for laughs:
I have occasionally over the last few months had blurry peripheral vision in my right eye. It's a kind of kaleidoscope effect and I can still see it whirling when I close my eye.
Probably totally incidental but I had a trn the other day when my right cheek and hand tingled and I struggled to get a word out for a moment or two, but lay down and was fine immediately afterwards.
I have numerous horrible neurological disaster scenarios running through my mind obviously, so will see a doctor, but any ideas?
