Without examination confirmation of a diagnosis is tough but it can be due to 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.Many cases of hives are "idiopathic," meaning no cause is known. Others may be triggered by viral infections or medications.
The mainstay of treatment of hives is antihistamine. Double conventional doses of non-sedating antihistamines such as Cetirizine or Loratadine may be needed to get symptom relief. Sedating antihistamines such as Chlorphenamine(benadryl) are used at night to get urticaria control.These antihistaminics are available over the counter but as your daughter is only 5 yrs old,so it would be better to consult a pediatrician before giving any medicines.Short courses of oral cortisone or steroids may be needed for short periods (one to three days) to settle more severe symptoms.Then a dermatologist has to be consulted.
You may also take Vitamin C along with the prescribed treatment. Vitamin C is a general anti-allergy supplement. It helps stabilize mast cells so they are less likely to release histamine.Application of calamine lotion will also help in soothing the skin.
Hope it helps.Take care and pls do keep me posted if you have any additional queries.
