I need help with removing my warts on my feet and finger.?

i had a huge wart on my foot for 2 years before i told my Doctor about it. last december my Doctor told me to use this acid thing that freezes the wart and then file. it has been 7 months now and in those months new warts have grown, the acid has been cooled from liquid to who knows what and caused a refill numerous times. i file them to the point where they bleed and now my Doctor is telling me to use duct tape which constantly falls off everyday and does not work so far( been 2 months since i started that) i am tired of these and want them gone quick. when i file them and apply the acid they turn black. can someone give me some advice or other quicker methods to remove these warts.
