M.D.
My son had this. To this day, I don't know how he got it, but it really bothered me. He first had some on his hands, then belly and eventually got a few on his face (about 3 or 4). I took his to Texas Children's dermatology dept and they did the treatment with the liquid nitrogen. Now, it may not sound like fun or sound like something you would want your child to go through, but it was the best thing ever. After about 24 hours it would scab up as though he had a small scratch and over the next 1-2 weeks, it completely went away. My son had about 4 treatments total. I would like about 1-2 months go by between treatments or I would schedule him as they would pop up. It is considered an outpt surgery, but is literally just an office visit. The nurse is also the one giving the treatment. They were very much qualified!!! This occurred I want to say when my son was around 4 or 5 years old. He is now 10 and after those few treatments years ago, he has not had this problem re-occur. So, if you are asking for an opinion, I would say definitely just take him in and let this do this treatment. We tried the creams and they did NOTHING! Plus, they were about $100 or so for the smallest tube. The treatment with the liquid nitrogen is worth it! Not to mention, in my opinion, the most effective and fastest way to get rid of it. Good luck!
