Have they sent you to a Neurosurgeon? If not, ask them to. And are you on anything for Neuropathy? Ask your doctor for something, such as Topamax. I didn't like Neurontin(Gabapentin) as I gained alot of water weight and felt loopy all the time.
It sounds like there is nerve impingement to me. Otherwise why would your right arm and hand be numb all the time? How can you "dream" that up? Are they all NUTS or something?

Have you had an MRI with and without contrast material? That's what you need so they can SEE the soft tissue.
I hope you get some PROPER treatment soon! You sure need it. God bless and please take care. Hugs, Lee
