I've seen a lot of neurology, and I'm sure what you have is called a Bell's Palsy. It's a common, usually self-limited, droop on one side of your face.
There are still neurological conditions out there that I haven't heard of, but I don't think you have one of them.
I'm not sure where you're getting your information from. Maybe you didn't hear the ER doc correctly. Maybe the ER nurse was in a hurry and her handwriting on your discharge instructions was sloppy. Maybe English is your second language.
But, as far as I know, this condition that you listed on your fax doesn't exist.
It says "Bell's Pussy".
If you do indeed have such an unusual condition, I recommend you either see my esteemed GYN colleague ER's Mom, or take your cat to a vet, depending on the circumstances.
See ya Monday!
