TENS UNITS will keep the worms stunned for hours of relief a day from wiggling worms. They are cheap (abt $25-50) & worth every.penny. the worms hate the electricity that runs thru them and keeps them still. I have to work and without the tens unit i wld be bed ridden 24/7. Get xtra 3" pads and wires and buy the blue cloth pads they last longer and prevent burn makrks on the skin. Until a cure can be found for people that have no help and have to work the TENs unit can keep u going!
