Hi Ed @njed, I have similar symptoms when I rub the side of my lower hip. Whichever side I rub or scratch seems to cause some tingling of the nerves down the leg into the foot. I suspect it's a nerve thing by touching something in one part of the body sends a signal out on the nerve to the peripheral nerves at the end of the line so to speak. Just a non medical observation and opinion 🙂 Similar to having our "own EMG test" without having to pay for it and it's always available!
