as far as tn is concerned,,every one who treats tn,but does not cure it,or know what causes it,,is wrong,,, curing it is right,,,,docs dont cure it,,so they are wrong,,they know no more about tn than we do,,why would anyone keep going back expecting a cure,,,the drugs only treat the symtoms not the cause,,not much of a life popping pills all day long,,,and a doc saying ,,i dont know what causes tn or how to cure it,,so we have to rely on our selfs,,
