"i had been using lidocain 5% patch for years and they really do work. they allow me to move without the major pain i suffer from spinal injuries and major depression. recently my insurance carrier sent me lidocaine patches manufactured my the mylar company. these patches are a complete waste of money .  the mylar backing is inflexible and do not move with the body. they fall off within seconds. the edges curl as you put them on.. i do not take narcotics for pain management these were my only help to reduce the pain. do not bother with the mylar brand patches they are useless."
