Wow, freaky. Best wishes for a speedy, and thorough recovery.
Kinda doesn't seem like an assault. I guess it might have more if it weren't for the fever thing. Maybe some kindof infection that caused sudden unconcoiusnees, followed by a fall to the ground, and thud? The concussion might then have contributed to the neurological stuff.
Weird. Here's to a rapid and healthly recovery!!
