My daughter has non itchy painless red bumps all over her back arms and legs only what could they be?

Many possibilities: You didn't mention your daughter's age or how big the bumps are, but the most likely possibility is probably bug bites, which aren't necessarily itchy.

If symptoms or a fever develop, you should see your doctor or a dermatologist and get a precise diagnosis. ...Read more

It could be heat rash, a reaction of the skin to warmth and occlusion from pressure. Some drug reactions can do that as can conditions like eczema and psoriasis. ...Read more
