Feels like I am being electrocuted...

I have been sitting here in the recliner and for the last few hours I have had a new sensation in my left foot, almost like I have stepped on a live electrical cord. If you have ever been electrocuted with a low voltage wire you will know what I am talking about. My guess is that this is progression in the damage to the S1 nerve root which is the nerve that runs to the area I am feeling it in right now. Since there is not much we can do about it I will just put it on the list to bring to the doctor at the end of the month.
