Hi M.,
I had a similar problem with my son with his skin turning red on his face, arms and legs. I didn't think much of it but when it got worse I spoke to the pediatrician who recommended that we see a pediatric dermatologist. We found a good doctor and I found out that my son had excema. We received medication (a cream) that we've used for the past few months and it has now cleared up. I suggest checking out a pediatric dermatologist because they'll be able to best assess what is wrong.
Good luck!
