Somebody on this forum with horrible SFN symptoms in his legs got a nerve block shot in his lower back to see if helped with his legs. No luck. Then he got one in his neck, and it helped significantly. The doctor said, "That's not possible."

Makes you wonder if there's something they just don't understand.

My neck and lower back are both a mess by the way. Moderate to severe degenerative joint disease in all joints, but there's no stenosis and nothing is touching the spinal cord. Can't be the cause they say.
