Constant itching. She bites her tail until it bleeds. She had an oatmeal bath and then I shaaved the hair off her tail and put olive oil on the skin. The skin is red,purple,and black, scabbed and flakey on small parts. She seems to have no relief.

Why did you shave her and put olive oil on her skin? Olive oil for itching?

Take her to a Vet!
