I have had 2 surgery myself for Chiari. First one went good then got a staph infection in the incission and the dura graph didnt take so they opened me back up again and redid the deed! I am like a new person! Now headaches are pretty good the odd bad headache not to bad though!
My daughter 16 just had surgery in December for the same thing she also has a Syringomyelia which i never had! and the Adontoid bone is turned in.(my malformation of the skull not a big deal) as for her today she started with some slurred speach and then a nasty pressure headache that seems to be lasting a long time no drugs touching the pain. I called the Neuro and he said not to panic not too alarming but to watch how she is and check in later on.
