My 7 year old son has had a rash for 7 days now. We were at the beach last week, which is where it started. Tiny red bumps on his face, shoulders, and chest; not itchy. I assumed heat rash. Today, we are back home, and the rash is no longer where it was, but there are tiny bumps on his stomach with scabs on them. Again, not itchy. I m not too concerned, but wondering if a trip to the pedi is necessary.
