My son is 3 & 1/2 years old. He has throat problem since last six months and taken antibiotics (Amoxicillin +Clavulanic Acid) 3 times during this period. Every time he complaints of runny nose sometimes block nose, chest infection, throat pain, enlarged tonsils, tongue papilla enlarged, with high fever. This is repeating frequently almost every 2-3 months. Kindly suggest.
