My 1 year old son has recently developed a rash on his legs and some on his sides consisting of small, red, pimply, :confused: raised bumps. We've gone through the usual suspects; new foods, detergents, etc. Nothing alongs that line has changed. The only thing that I can figure out is that it is a concrete allergy. Let me explain. The bumps started out on his knees and lower legs after a family member let him crawl on a bare concrete floor in our farm shop. I've heard of allergic reactions occuring when coming into contact with wet cement/concrete or the dry powder, but is it possible to have a reaction from dry, hardened (for about 3 years now) concrete or am I grasping at straws? My son's little legs look terrible! Any info or insight is greatly appreciated. TIA!

Are you in a rural area? Could they be chigger bites?

What about heat rash?

Sounds like heat rash/hives. That is an internal allergy that certain things trigger it from coming out. My son has hives like that and I guess it was many things until his allergist comfirmed what it was.

My guess is it was something on the floor that caused the reaction. You said it was a farm shop? Is there anything that gets tracked in from the outside that might cause a reaction?

My child has developed the same rash after crawling on our concrete outside. I was wondering if any of you out there knows how to get rid of it. I've put Neosporin and that seems to help, but it still looks scary!
