Hi R.,
I hope that your son is ok and feeling a lot better now. My suggestion is that you take him back to the doctor and make sure that he isn't in any pain and see what the doctor says about the night terrors-- maybe they know some tricks to help him through this tough time. As far as comforting him, I would make a tape recording of you singing to him so he can listen to it throughout the night. You could also buy him a special teddy bear or soft blanket to hold. If you sleep with it for a few nights it will have your smell which is always comforting for babies and toddlers. Good luck and I hope everything is ok.
