What is happening to my hamster?

I found my hamster in his cage, wobbling and having trouble walking. I did a little research and found that he might be going into hibernation. I did what the forum told me to, and warmed him up. I noticed his pulse rising and all of a sudden, he jolted as if he were having a seizure. He urinated and is now back to being still but this time, he is breathing fine and his eyes are wide open. What do I do from here?
