You need to find a new doc ASAP. My NS is the chief of the neurosugrial department at the hospital I work at...he had my surgery scheduled and set within 3 weeks of our first appointment.

Chiari is a very real thing that makes life very difficult. I suffered for YEARS before my PCP sent me for my just in case MRI. She didn't even think it was smart/a good idea to even see a neurosurgeon. She recommended against surgery.

If I hadn't had the surgery, I would have had a stroke by now. And I'm only 27. My NS said it was damn lucky I saw him and got under the knife when I did.

Get to a neurosurgeon. Have them look at your scans. If they say the same thing, keep going until you find a doctor who takes Chiari seriously.
