I'm sorry you're suffering so much. I hear you and understand your frustration. X-ray's don't show anywhere near enough to rule out spinal problems. I hope you can get an mri to see what's going on.
I too have neck, shoulder, arm and hand pain. The single thing that helps me the most is heat. I almost live with my heating pad. The one I use is shaped like a cape and fits around my neck perfectly. I think there's a picture of it in the Helpful Gadgets section.
I also use hot baths and showers. I stand under the shower, hot as I can stand it, until I start to run out of hot water.
It's very important for me, to never get a chill in my back. That sets up spasms I have a hard time getting under control.
I've also found laying down for an hour through the day helps. Using pillows to support my arms when I sleep. Pacing my activities. Daily walking.
Sorry this is all about me, but you did ask for suggestions, lol. If you can tell me a bit about what seems to bother you the most, maybe I can offer something that might help. I can try anyway Aela.
I'm sure others will be around to offer suggestions. It is always a little quieter around the site on weekends, but people will be by.
I know everything I offered is pretty basic, but sometimes the smallst things can help alot
