What's wrong with my cat's ears? She's miserable.?

Question by Narla: What's wrong with my cat's ears? She's miserable.?
I looked with an otoscope and 1 ear has a TINY bit of yellow, perhaps earwax in it. The other has brown stuff. The 1 that looks normal is the one she is rubbing.

She has watery eyes, no sneezing, her ears are lying to each side. She is miserable.

Last year the vet said that she is allergic to fleas. I gave her Front Line today. (I always hold off during the winter, since she stays indoors when it's cold out.)
