I'm receiving ideas from myriad places containing the traditional wisdom of how to treat this sort of head injury. It's not a conventional injury, for one. It's got some features of damaged bits, but other parts seem to be fine. Still others are really worrysome, such as the intermittent hallucinations. It looks like I'll be doing inpatient stuf for a day or so (maybe 3-4) on an EKG and EEG, and get my MRI redone. It would be so nice if they found something. Of course, "something" is going to be like "You have a four centimeter mass on your prefrontal cortex. While it's probably operable, there's a margin of morbidity."
Fortunately for all concerned, it's never lupus. So, we're safe there.
