Hi. Greetings. I would like to examine your son or atleast see photographs in order to decide the line of management. There are ways to make a procedure relatively painless so don't worry. Are you sure they are warts or are molluscum lesions.? How old is your son and how many lesions are there? Kindly furnish these details on private chat and I shall be able to suggest any alternative therapy if appropriate. Hope this helps. Best wishes - Dr Govind S Mittal
