Hello,
The symptoms are suggestive of hives. Hives (medically known as urticaria) are red, itchy, raised areas of skin that appear in varying shapes and sizes. They have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours.
The mainstay of treatment of hives is antihistamine which may be necessary for prolonged periods. Ti cifnrim the diagnosis I suggest you to get it evaluated from a pediatrician.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
thanks for the reply and concern. it happened so that my husband brought a car sun shade which was coated with some powder. our son was playing with it when he developed itchy rashes all over the body. from then on he's been getting these rashes which are non-itchy but appear mostly on the face and disappear after a while. he was treated with anti-histamine but with no success.
can someone pls. help.

Geeta,
Are your sons red patches limited to only certain areas, like his hands, and arms? Or, are they all over? Also, is the skin kind of dry where the redness is, and does the red areas feel a little warm? ...If you answered yes to most of these questions, he may be washing his hands to much, and, or washing with the water too hot. The same happened to my son last year, and it lasted for 8 or so months before we figured it out. However, if this is not the answer, he may have developed an alergy to a soap, laundry soap, lotion, or something he uses regularly; or even a change in diet, as well as developing alergies to food he has always eaten. My sister developed an alergy to Dail soap, after years of use. If none of these are the answer, you would do best to take him to a demotoligist, and a alergist. I hope this helps, and I hope it is nothing serious. Let us know how the little guy is doing.
