My 4 yr old son has clusters of raised flesh colored bumps on his elbows and knees. They itch him sometimes. I can t tell if the scabby looking thing on some of them are from his scratching, or if they just turn that way. I noticed the bumps a week ago. They are not going away, and they are spreading down his arms and legs. I tried to put hydro cream, but he says that it doesn t help. I was just going to take him to urgent care in the morning, but would like to know if I should or not.
