Yeast infection in the ear??

So Dex has a yeast and a bacterial infection in his ear. Poor widdul buddy. I took him in on Saturday and they swabbed a big chunk of gunk out of his ear...'twas really nasty looking. I have to clean his ear with gauze and cleaner once a day and put a medicated cream into his ear canal twice a day. He HATES it! He yelps and writhes and gives me the saddest look he can muster. We have to do this routine for only oh....12 more days. I can already tell he is feeling better though, he isn't scratching at it as much and it isn't producing as much gunk 2 days into the medicine. Oh and I'm only out $200 for the vet visit! #$%@%#@% (although shots were included)
