thanks tayla that is really interesting. i will try and find out about that - has not come up on my various searches but will look for it specifically now! i have oral ketamine solution but obviousbly much weaker than the iv either subanaesthetic or at coma level doses. i am sure that interstitial cystitis as an umbrella term has a population with the same neurological dysfunction and changed processes as other disorders like crps so the treatments may ultimatelt help a lot of pain now classified under various 'syndromes'. i wish the focus was on processes not categories!
i am corresponding with dr schwartzman's pain nurse specialist and hoping to make an appointment to go over to see him for initial assessment with a view to the full coma treatment. in the meantime i am trying to find out as much as i can about what is going on and the neurophysiology of this kind of pain.

many thanks, take care,
sarah
