I just woke up with no pain and no sign of any visual disturbance / migraine - and now it is back again. I am SO pissed off. Thank goodness I have developed techniques over the years for looking at things out of the corner of my eyes so that a hole front and centre in my vision (a scintillating patch where I cannot see what I am looking at) does not stop me from living/coping. Sadly, though, much of what I want to do is vision related or needs me to see what I am doing. Back to bed again with co-codamol, methinks.
