My son 2 yr had rashes 2 weeks back, I thought because of change of soap.. later he had fever, runny nose and cough. Doc prescribed antibiotics, paracetamol, frisium if he had high fever and cough syrup. He had febrile seizure once. Now he is itching everywhere from head to toe non stop. No rashes. Its totally annoying for him. Now he is under antibiotics and cetrizine. But no change in itching since 2 days.. and doc also advised circumcision. What would be the reason..
