Hamster fell down, showing some symptoms, please HELP!?

Hopefully your hamster is just in shock. But there is a chance it may die, if you say it isn't moving make a comfy bed and lie it down you may just have to accept the fact that this has happened try not to go down the self blame route. When my budgie was in its last hours i layed it on a heart shape pillow and lay it next to me until it died. Hope this helps.
