My daughter is 5 years old and for the past 3 years these same rashes appear on the back of her legs behind the knees and in front of the elbows where her arm bends together. And they always come back on both sides (L/R) of her body. These rashes come and go. At first we thought it was food allergy and when we would take her off of milk/dairy the rashes would go away for a while. Then when they came back we would take her off of wheat, thinking it might be a food allergy. The rashes would go away then come back. We've taken her to 3 of the best skin doctors we could find and they said it was scoriasis or exzema, but the medications the wanted us to put on the rashes would cause the rashes to inflame and was extremely painfull to my daughter. Can some one please help me.!? photos are attached.
