Hi and welcome to the Chiari forum.
I am so sorry to hear you are having such a bad experience with your Dr....and your recovery.
Not all NS's know enough about Chiari and the related conditions that typically come with it to really treat us...but they do anyway and then do not offer the appropriate follow up care.
We do have a list of Drs for your country but I do not know if any are close to you or not or if they are true Chiari specialists...the list was compiled by members here of Drs they had been to, been treated by and liked.....so it is here for you to use to research them to find the right Dr for you. If your current Dr is on this list please send me a PM with the name to keep negative comments and Drs names off the forum.
