That's a message from my cat wishing you well.

I also have little knowledge, but my surgeon that clipped my unruptured aneurysm, told my husband that the brain gets very '****** off' when someone messes with it and it can take a looooonnnngg time for it to calm down. As Lynn says, your mom's brain may need some time to rest.
I will keep you and your mom in my thoughts and prayers. You're going through a very stressful and painful time. Please keep us updated.
