Thanks for the query. Meet a Dermatologist to get the diagnosis confirmed. It appears as viral wart and will need some form of treatment. Delaying may lead to further spread. Of the various options like electrocautery, radio frequency , cryotherapy and curettage, I feel cryotherapy will be a good option. The Dermatologist will suggest a treatment option based on the body part affected and considering merits and demerits of each procedure. Warts may recur after a treatment and you need to repeat the treatment. Higher doses of zinc helps to prevent a relapse.
