I am having trouble making sense of what all has "actually" been done by a vet and what diagnoses were made.

I read somewhere about an ear infection in OP's posts. I know an inner ear infection will cause strange behavior like head tilting, walking funny, or it did in my yorkie. She even acted like she had trouble with her depth perception. Again, I know OP mentioned this and did get treatment, I think.?.?

You also mentioned it returned, was the source of the infection ever discovered?

ETA: The above post may be totally useless, I went and re-read some posts and see liver is being looked at as cause, I think.
