Q: My one year old son is having swelling on eyelids and forehead since last five days. Is it a symptom of allergy?

A:Swelling of face and eyelids may be due to allergy, but there are other causes as well. Before taking any drugs, the minimum that is required is a urine test to see if he is losing an abnormal amount of proteins in urine. This is one of the important causes of swelling.
