The only time that a hedgehogs quills can hurt is if you push your hand into them while you are petting him, or if it is rolled into a ball, and its quills are raised in defense. Also only if you are dumb enough to pet them backwards, which would be very uncomfotable for both the handlr and the hedgehog.
i think that they have 400 spines
yes
No, unlike porcupines, they have hollow tubes on their back.Hedgehogs are easily recognized by their spines, which are hollow hairs made stiff with keratin. Their spines are NOT poisonous or barbed and, unlike the quills of a porcupine, cannot easily be removed from the hedgehog. However, spines normally come out when a hedgehog sheds baby spines and replaces them with adult spines. This is called "guiling" When under extreme stress or during sickness, a hedgehog can also lose spines.

Hedgehogs have spines to protect themselves from predators and threats, when threatened they curl into a ball with their spines sticking out.
No. They may, however, be contaminated with dirt and bacteria.
Yes, hedgehog quills are modified hairs.
the hedgehogs spines helps him defened himself (fox,wolves and other animals) xx xx thanxs for the question
They're vertebrates, they're born that way. An animal looking like that and living like that has to have some sort of supporting structure, and for the hedgehog it's a spine. Or maybe you're thinking of the things that make them prickly, not the backbone. There are plenty of animals out there who would make themselves a meal of a fairly slow and harmless animal as a hedgehog, so the spines developed as a defence. If threatened the hedgehog curls up into a prickly ball, and anyone trying to bite or claw it end up getting hurt. THe hedgehog ended up taking that route instad of developing an ability to run, hide or bite back.
