Electromyogram

I had an electromyogram.  Electrodes are hooked up to the body and shocks are given, the speed at which the signals propagate is reported.  In good health a serious twitch or jerk can be expected at higher amperage.   I'm good from the knees up.   Below the knees I am a wreck.   I can point but not flex my left foot.   Lot's of diseases were ruled out.   I'm telling you, hypoglycemia and/or vitamin B12 deficiency is sufficient.

They decided to put me on a daily regimen of calcium and vitamin B12 delivered intravenously.  Ok, let's go.  I'd like to be able to walk out of here.
