Studies have found conflicting results of the effect of zinc on viral warts. Well-conducted studies are needed to clarify these early results. So we cannot confirm whether zinc is beneficial in warts or not. Regarding the treatment part, many modes of treatment are available. For small warts, several medications(like podophyllum resin, Podofilox (Condylox), Trichloroacetic and bichloroacetic acids, Imiquimod 5% cream and interferons) are available, which can be applied directly to the surface of the warts. Other treatment options include electrical cautery, surgical removal, Carbon dioxide laser treatment and electrodesiccation.
In my opinion you should talk to a cosmetologist/dermatologist about the treatment options.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
My 12 year-old son has been having the same problem. After the second visit to the dermatologist, she suggested adding zinc to his diet. I'm going to go through with it and see how it works! I know Zinc affects the stomach, so I'm going to give him his supplement at meal times.
