Shar pei pup help please?

We got a little girl shar pei last week she's 14 weeks old I noticed a lot of wax in her ears and they're quite smelly but she went to the vets yesterday for a health check and her first needle.. and the vet said nothing about them ! They're obviously irritating her she's always shaking her head and scratching them with her back legs, any help pleasee? Thanks a lot
