But RRae, Tchr012, or PoohAC might have thoughts about it, frankly, I wonder whether your squat may have somehow loosened a lead and that is what is producing the shocking [kind of like I would get pre SCS when I used Tens and a lead would come out of one of the adhesive pads and shock the dickens out of me].

Hope you get in touch with your rep soon because this kind of phenomenon just has to be irregular.

Caring,
