Anyone's children have this? My youngest had a few, they went away. My middle has it under his left arm pit and now it looks like it's spread, almost to a rash. Doc said it's viral, back when he saw it in November, and it can take up to 18 months to go way, so I was waiting it out. But it seems to be spreading. I think I'm going to take him back to the doc. He has some eczema issues during allergy season, so I have some cream I am putting on this to keep the itching down, but I'm not sure what else to do. Ideas? anyone with experience?
