I assume flight or fright response kicks in....and being unable to flee....with being choked and all (she did have other bruising on her body).
The ER said she had a rigid neck ***and all other muscles in her body*** were rigid. They still are.
I've had a seizure before. My neck was the most painful part. She was having continual, and no doubt much more intense, seizures.
Even had it only been her neck, and no seizures... I got whiplash years ago from falling forward out of my rolling chair that lost the front wheel, and I didn't even hit the ground. Her fall was even worse.
Then you still have the severely low potassium that no fight or flight response would account for.
See above for the rest.
What bruising?
I do my best to avoid comment about this, but it's hard. I just think the theory is so full of holes, the best that can be said is that it isn't worth the distraction it causes from the real points:
Give her another chance at therapy and testing so she may be able to eat and drink on her own.
That should be focused hard and driven home, IMHO.
gotta run : )
You've reached your conclusion, and now you're dilligently looking for a way to intellectually justify it. It's supposed to work in the reverse.
