My son is having skin itching without rashes.. I see him scratching head, arm, behind neck and foot. No history of fever or infection. I suddenly feels his appetite increasing. Sometimes he says abdominal pain. I saw white particles in stool but I dewormed him last month. Currently he is on anti histamine.. same type of itching happened last year he was adviced banocide syrup and anti histamine almost took month to cure. I'm really worried What would be reason. What medication for abdominal pain and itching.
