I consider myself extremely lucky to have as a doc one of the world's leading, innovative thinkers who specializes in spinal fluid issues. She is the one who diagnosed me with PTC, and she is a Neuro-radiologist.
Billings???? You sure must like the snow!! Beautiful country, but damn, it gets cold up there!!
I'm in North Carolina where the lowest high temp in the middle of winter is around 50 degrees!!
And yes, IIH, or rather PTC, is on NORD's list of rare diseases. But agree with Deb, I bet there are a whole bunch that are misdiagnosed, and often with Migraines. Lucky us.
