i feel exactly the same way.
Hi..having the 6 mm herniation from chiari is not a sentence to have surgery...but the obstruction of CSF and overcrowding and symptoms may be...how it impacts ur overall health is more important that the size of the herniation.
No one wants brain surgery...the risks alone r not something that we would choose for ourselves.....but, not having surgery can be just as bad for u if ur chiari is affecting ur overall health.....
Be open, look at all the facts...wait for a true chiari specialist to guide u.
and most of all RELAX : )
