Hi, welcome to BYC!
Sorry your girl is having trouble.
I have been wondering about an ear infection in one of my birds, though I think it's wishful thinking and actually a genetic tick. But do you mind sharing how you diagnosed yours please?
Here is a symptom checker tool. It list ALL the possibilities of illness that can correlate to the symptoms you put in, and then you work to rule things out...

Could be infectious Coryza, Mycoplasma, sinus infection, swollen head syndrome, New Castle's, conjunctivitis, and a few more.. even B6 deficit. Not eye worm as far as I can tell, but also here to learn.
Hope she feels better!
