My poor, poor cat!

Well, I posted a while back that I thought she had ear mites, but when they looked at her ear (which she had scratched raw and infected), they saw that it wasn't that. They didn't know what it was, but gave her a cortisone shot and antibiotics.

Now, a couple of weeks later, she has scratched the side of her neck (had to take off her collar because it was irritating it (won't get more graphic detail), and now I have to take her BACK to the vet, which she flips out about. AND, I bet it will cost me another couple hundred.

WTF is wrong with my cat? If they cannot tell me, I will freak out.
