Sometimes if you treat the little suckers they spread. If its not causing you any pain i would leave it. Bazzoka can take up to at least 6 months to blast the beauty. You could have it frozen at the quacks,.... or "wait for it" apparently rubbing banana skin on them gets rid, cant say i have tried it though. and lol i read online if you put duct tape on for 12 hours, remove and reapply that will get rid too. (Bizarre). And contrary to belief they arnt meant to be spread that easy, they are caused by a virus and most prone when your run down. They are flat warts basically. Good luck anyway
