My 23 month old has had a rash for over a month now. It appeared the day after going for a well check & shots. It started as 1 single line of red bumps. It spread all over her left side of her chest, stomach, back, arm & leg. She complained of her belly hurting. I took her back to the Dr a week or 2 ago & he said it was probably viral, gave an antibiotic & cream. The cream seemed to be helping, but it still gets worse some days. Any ideas?
