Extreme neck pain please help?

I'm afraid I don't know anything about Scoliosis. But, until you mentioned that it sounded like a pinched nerve (which is something I do know about from personal experience). I would see a doctor. In the past I have been given a neck brace to wear (only for a few days). That will keep your head and neck still and keep those sharp, burning, shooting pains from being so intense. Your Dr. may also prescribe pain medication or a muscle relaxer. Best of luck to you friend. I hope you feel better soon.
