Daesin,
Having read through my post again it comes across as a bit terse and snappy, I did not intend that - 3 Cluster Attack day - and I apologise.
Thank you for your concern, I was (and am) actually propped up on my side with my left hand covering my left eye to counteract the double vision caused by a brain lesion…
Anyway, Lidocaine Infusions and Ketamine, remember these for discussion with your new Dr. Both are anaesthetics and have been shown to work well on severe, chronic neurological pain. They even dull down the trigeminal parasthesia I constantly suffer, which can only be described as the 'pins and needles' pain you get in your arm when you lay on it wrong - and the feeling is just coming back. Try explaining to your Neuro that it covers the left side of your face, and when it gets into your nose you want to rip it off and shake it around to get the feeling back - and not sound insane!
I hope your new Dr finds an answer for you, your story shows that one step can change our world.

Dave.
