Well being an ex electrician I had to try this. Just did it yesterday and most of the pain I was having is gone. Don't have to have any expensive stuff, even though they do sell it on line. I took a piece of 12 awg wire stranded long enough to go to ground hole in a socket (not a lady Rob) to my foot on the floor.
Stripped about an inch off of one end, doubled it back over itself to fit snugly in the ground hole. Then stripped about 4" off of the other end to set my foot on.
The ground hole is the round hole on an outlet. It will only work if your house is properly wired, and grounded.
PS Don't stick it in any other hole. (That's what she said) LOL
