Yes, many hugs and warm healing thoughts your way chicy724 and Daisy.
It sounds like she has gotten and is continuing to get the best possible veterinary care available. Not sure I can add any useful advice to that plus to the multiple suggestions from members here, but I surely will hope and pray that the vets can find a cure for her.
Much love to you and Daisy. She's lucky to have such a caring person as you in her life.
