Address the shock while you hold it !!!
It shocks you as you hold in in your hand tried a rubber glove it didn’t work to the area I was trying to send current, removed glove and as I treated the area while with other hand kept getting shocked. Your the ground if someone else holds it and tries to treat an area doesn’t work , so one has to put up with the pain If getting electric shock While  holding it to treat the area<br />This is the only set back that really needs to be addressed
