Son fell on wrist out tree stand he can move it but it's starting to bruise n hurt should i get it x-ray ?

Ice the wrist: And if still hurting tomorrow see your doctor to see if an x-ray is needed.

I would: Bruising is a signal there is bleeding from somewhere & it might be a cracked or broken bone. There bones in the wrist than can break without dramatic trauma & not be easily found by x-ray. If a break is there & not treated appropriately it may cause limitations to mobility later. I would chill it for now & keep it elevated above the heart. Have it seen in the next day or two.
