--in the process of doing the needle EMG/nerve conduction studies,did they do Alan's paraspinal musculature in the lower back?

This might point to disruption of signlas between the nerve roots and the nerves they serve that eventually go down the legs. (I just had one done for my weird leg/sacral/pudendal thing going on--all normal--and though it's not the most pleasant thing in the wrold, the discomfot is generally fleeting.)

As I've written before, I've always thought that Alan might have mutliple things going on--I still think that an autoimmune etiology for some of this is likely, given his other medical history, and that there may be "double crush" exacerbating the symptoms if there's any compression at all in his lower back or in his legs (speaking of which, does he have a recent lumbar MRI?).
