...or not.

So. News. Per the radiology report:

My herniation (listed this time as 6 mm when previously 5 mm - chalking that up to human error) is more consistent with cerebellar tonsillar ectopia than with Chiari. According to what I've read though, the only difference is the ectopia is smaller and asymptomatic, while Chiari is larger and sometimes symptomatic. I guess I don't understand the difference.

Very mild disc degeneration that has nothing to do with anything.

The study showed no abnormal CSF flow BUT my posterior CSF space is visibly narrowed and there is an isolated "foci" (hah, big words) of hyperintensity in my left side brain. According to the report this could be from migraines (possibly), diabetes (don't have it), hypertension (not sure if they're talking blood or brain, but I don't have high blood pressure), or vasculitis (not a clue).

They also noticed my thyroid gland was odd: "parenchymal volume loss" is the term they used. Hashimoto's came to mind but I haven't researched it enough to know if that's a possibility for me.

Back to square one. Again. There is *something* neurological going on, but my PCP is just as clueless as I am now. She doesn't think it's something surgical, I can drop Dr. Hahn (hooray!). Multiple Sclerosis was suggested but I refuse to let myself think about it. Next step: call neurologist and make another appointment to be poked, prodded, and squinted at once more. Square one. I hate square one.
