I'm just curious how many have been told by their doctors or neurologists that surgery, although an option, is not recommended? I was diagnosed in 2007 with a 13 mm tonsil. Until this week, i've been told that Chiari does not have any symptoms, that it's all in my head (duh), or that there is nothing wrong with me. All these problems have been chalked up to having diabetic neuropathy, carpel tunnel (which i just had surgery for), fibromyalgia, or chronic fatigue.
