Hi , I have being having this an ala wart for over 4 years , I had consulted a doctor and he performed an intradermal implant , wherein he burnt a wart and inserted it into the skin . He said this would built body immunity and the warts would eventually go away. I wanted a long time but the warts didn't go away , what are my next options and are there any oral drugs that I can take , as I live alone and can't apply anything on my back. Please help I am worried as some times of warts can cause cancer etc.
