This doesn't sound normal to me, and he may have a problem that needs to be looked at by a veterinarian. Hamsters are kind of delicate when it comes to medical problems, so the sooner you have him looked at by a doctor, the better it will probably be for him, as there may be only a simple treatment for what is happening.
Here's a good website from Google (there are more, if you type in "Hamster Care")
