If it is molluscum, my son had these. He had them for about a year. I tried over the counter natural remedies to no avail (thuja ointment, tea tree oil, silver gel). I have two other kids and were afraid of them spreading to his brother and sister. We finally heard about a pediatric dermatologist who uses beetle bug juice to painlessly get rid of the molluscum. He had one treatment (literally a pin point of juice was applied to 5 - 6 bumps) which provoked a response from his immune system and all of the bumps were gone within a few weeks. He had lots of bumps on the backs of his legs and above his armpits. PM me if you have any questions. I forgot to add that he wasn't left with any scars. Also, our pediatrician had recommended seeing a regular dermatologist who would burn them off. No way! I'm glad I waited and went to the pediatric dermatologist who used the bug juice. Totally painless and no scars!
