This about allergy. My sister 5 years old has been suffering from this for almost a year now, everytime she takes a bath red patches would appear all over her skin. i noticed that Everytime she s in a cold place the redness would start to show. She was scratching her skin so she acquired a wounds, we had her checked and they said it was food allergies we avoided every food they said (dairy products) but it did not stop. And its getting worst. What do you suggest we do? Thank you. - Mika
