If you are using dusty bedding your hamster may have become allergic to the dust. My hamster, Sherbet, became allergic to carefresh as she wouldn't stop sneezing so I took her to vets just to be on the safe side as when she sneezed she seemed in pain and they gave her antibiotics and after a week she stopped sneezing. So if I was you I would try to get to the vet just to ensure it nothing more serious.
