Last year in march i got diagnosed with molluscum only on the right arm so i got a laser operation done as they were so many so after 6 months again they reappeared so doc gave me a med name tretin-0.05% but due to pregnancy she asked me to stop using that and asked to get it removed either through acid or using anaethesia cream..so i have attached a pic along kindly suggest wat need to be done as i am lil worried about the cause that why it happens again and again
