i haven't try ACV, the painful of using lime stone paste is the highest level and i'm scared of using it again. i have tried once and for only 5 minutes( i stop it cause i can't stand the pain) i rinsed of it by water. the wart melting and seemed like burn. at the moment i wish i could have a local anesthetic. now i'm using Oxyfend and the 1st tube is already empty. still has no difference, but i pray to God to be cure, i still have a big hope on this product. the wart is getting spread on and i'm still waiting for the miracle.
