Hello,
My name is Jon and I am now 3 yrs removed from Chiari I surgery. I have been doing great until recently, when I started to experience a soreness and pain in the back of my head and neck as well as a sharp shooting pain down the left side of my head near my left eye.
I have found a neurosurgeon here in North Texas and am currently undergoing tests including an MRI, CT Scans, X-Ray, and one that really scares me: Nuclear Cisternogram? Has anyone ever had this test and what exactly are they looking for?

Thanks in advance!
Jon
