Welcome to Neuro Talk. There is alot of dicussion on this subject on the site. Tap in Chiari malformation on the search bar up at the top of the page. This will get you to that forum. Don't hesitate to ask away, any of the questions you have.
I am sorry that this has turned out to be a mess that you have to fight for your care. Its good to know you have a neruo specialist in your corner now. I also agree with the former post, don't go to the chiropractor unless your neuro surgeon would give permission for. Thank doc. however should be thanked for setting you on the right path to get help. Also the idea of a lawyer is a good one. I really hope this resolves quickly for you. You found a good site with lots of help and information. Again Welcome to NT. ginnie
