I just wanted to say welcome to Neuro talk. If you have been diagosed with Chiari,, I would go for another opinion and not take more injections unless you are positive it is the right protocal. I hope a good solution can be found for you. I also had heard that the injections arn't necessarly for this disorder. I have not looked at the hard research yet, but you can google it for a little more information. My best wishes for you. ginnie
