Thanks for reply Dr Diana.
I will purchase your book on Amazon UK so that I can pay in sterling and look forward to reading it.
In the meantime, do you have any ideas about convincing doctors in the UK that I need urgent help with this head/neck instability problem? I feel as though I am at high risk because of brain stem compression and the chiari 0 causing a CSF blockage and excruciating pain but nobody seems to understand my symptoms or can advise me what to do to give me some quality of life. Do you have any contacts here?
