Dear Roger:
I recommend the following:
1. Get evaulated by a good neurologist with expertise in neuromuscular disorders and EMGs at an academic neurology department near you to look for the possibility of an active nerve root compression, which may potentially require specific local measures (mainly surgery).
2. If evaluation 1. is a negative or shows insignificant root involvement, consider getting an evaluation and treatment from a chronic pain management program. It often helps.
Good luck.
