Teething

Se
Is anyone else struggling with a teething baby? 
My little boys four months and he's teething really bad constantly sleeping constantly wants to be held if I put him down he will cry. His cheeks are so rosy if my hand is near his mouth he will grab it and munch on my hand :( he's in so much pain during the night he wakes up crying cos it hurts.
Any remedies? Any advice? 
Any stories?
