Have you heard of Rolfing? Hellerwork?
Ice and painkillers for a day or three while you get the inflammation down is a good idea if you get a doc recommending it. Then....
Finding a good structural body worker might help. When I have people in so much pain they can't move I find the affected nerves and follow them from the spine to the periphery of the body and start working the musculature there. By the time I get to the spine things have usually loosened to the point that movement with much less pain is possible. So for the cervical spine I would generally start in the hands and arms, forearms especially, ive found, to influence the upper ribs and shoulders. Pectoral or chest muscles to influence the upper back and sometimes the neck. Latisimus dorsi if there is pain lifting arms up and over the head, or mid to low back / rib pain. I find if I can create some space in an area not so inflamed it helps the stuff closer to the spine on that nerve to relax.
So now that I've said all of this- go easy and stay away from the neck and spine- let the pros handle that. And don't hammer at things for hours Little bits at a time, and then ice where you have worked.
My teacher is this guy http://www.capstonemethod.com/
he has some you tube videos up, check them out. maybe it will at least give you some alternative ideas for therapy. I've seen this type of bodywork work miracles. An osteopathic doc who does manual manipulations could also help a lot and be covered by insurance. Exploring the emotional connections to the throat chakra may be of use as well??? Wish I could be there to help out. Good luck!
