I'm glad that your daughter has had a good outcome. I am reading reading reading. I'm just baffled because my Orthopaedic surgeon said that he saw nothing on my MRI report that would be the possible cause of my headaches. Then I read that. Maybe it's simply because Chiari is not in his realm and he really doesn't understand it. Here's is one thing that is most concerning to me. I also post on another board and there I read that someone had Chiari and they corrected it first before they did the ACDF surgery to prevent complications. Now I've done this in reverse and wonder if my symptoms now aren't because of this. Thank you so much for the reassurance. I really needed to hear that Chiari surgery can have a good outcome if I have to go that far. I've asked and asked and can't seem to get very many questions answered. So I cannot thank you enough.
