So a few months ago I asked the pediatrician about these bumps and she had no idea and just said keep an eye on it... in certain lighting some of them are shiny like they scarred. They’re raised and don’t seem to cause any discomfort to him but it hasn’t gone away and it looks like more bumps are showing now. Any ideas???
