Answer
Wow. That has got to be one of the longest sentences I have ever read with no punctuation. This makes it really difficult for me to read your question.

She sounds like she is experiencing what we call a 'neuritis,' which is basically a nerve pain on her back. That is the most common place for it to be, but it can be almost anywhere on their body.

Cats with this pain will run, jump on things like they are insane, turn in mid run, whip their tail around, have their eyes all dilated and sometimes will vocalize loudly.

On the other hand, it could be that she is simply scared, or she jumped off of something and hurt something and this is how she is reacting to the pain.

You need to get her into the vets to have her looked over. Only your vet can prescribe some steroids to calm the nerves down and make her a happy cat again.

Now that is just a suggestion of what it MIGHT be, but there are many things that is COULD be.

That is why you should take her into the vets.
