I need help getting rid of some stubborn warts that won't go away. I've tried EVERYTHING. Please help...?

I have tried almost everything to get rid of the warts I have. I've used salicylic acid pads, liquids, and ointments; liquid nitrogen; duct tape; and I've even been to the dermatologist. The only thing that seems to have even remotely helped is the really aggressive medicine the dermatologist used, but unfortunately my warts are still here (and more have decided to pop up...) and I won't be able to go back to the doctor's until September. I want help now because I am sick of feeling diseased and would like to be able to look at my fingers and toes and be proud of them... If you have any help or advice at all, please please PLEASE let me know. I would be very grateful. Thanks.
