Yes, it sounds like fleas to me also. Sounds as though she developed a severe case of dermatitis from the fleas. Revolution always worked well for me when I was rescuing ferals but whatever you have at your disposal should be ok. Except for flea collars. It's been my experience that, not only are they not effective, years ago one of my cats lost her fur where the collar had been. Don't use them.
