Hi, I am sorry, I am not a doctor. I wanted to tell you that my family has been through the same testing that your wife has been through. We live in Louisiana and my nephew has seen 3 doctors here and then we went to Houston. Houston is who diagnosed my nephew with Chiari. However, would not do anything until he had an "episode" (heart attack or stroke). He then went to North Shore Long Island Jewish in New York. The doctors there are amazing. My nephew was playing 3 days after his brain surgery and 2 days after his back surgery. My sister was just diagnosed yesterday with Chiari. My best advise to you is to email the doctors there and tell them your story. They will either email you back or give you phone call. I wish you the very best of luck.
