I am sorry you are not happy. I told you it sounds like he has encephalitis. I also gave you a womans email who has had years and years of raising squirrel experience and would be more than happy to help you as she has helped me many times when my vet has been unable to. Squirrels are not a domestic animal so people with hands on experience sometimes can be more helpful. I have raised a lot of them myself and any time they started with these symptoms it was encephalitis. We even suspected rabies in one when it did this, seizured and died. After testing it it was negative.
