My 16 month old daughter has a 3/8" red patch on the right side of her stomach. It has small, raised, almost clear looking bumps on the red patch. Maybe about 10 bumps total or so. That is the only spot on her body. I noticed it a few days ago. Today, my daughter threw up several times and can't keep anything down. I'm not sure if they are related, or she could of had a stomach bug that was unrelated. Should I take her to the doctor to get the rash checked out?
