Andrew had the same problem with his at first. I think they feel threatened so they bite and hard enough to draw blood. We just continued to handle her and pet on her. Here's a kiss for the boo-boo.
My first hamster was really mean and bit me all the time--and HARD! so we took him back to the pet shop and got a new one. I don't really remember all the details because i was 5.... years later my mom told me they probably fed him to the snakes.I don't know if you can get them to stop biting, but just getting him use to be handled seems like a good solution.
that wasn't very nice of him! but he's super cute!
