Sounds like migraine to me too. I had one 2 days ago and couldn't talk, words kept coming out backwards, jumbled up and making no sense at all. I had a blind spot on my right, it's usualy my left, and couldn't see my right hand. Daylight was too bright, noises were too loud it is just thoroughly miserable! It's interesting what you said about discs, I have two prolapsed discs in my neck and at least one in my lower back. I know if the discs move they can cut out the blood supply to my brain and I pass out, literaly drop like a stone! I then get a migraine, but I can get them without warning, like the other day. One of the other things that causes mine is a sudden drop in blood pressure ie if I get a shock however mild.
I'd go back and discuss it with your doctor if you can get them interested!
Good luck
