Hi this is lokesh my son is 8 years old from last couple of months he has suffering minor problem which is while taking breath, I took him to ENT doctor, and he suggested for x-ray and then doctor said every thing is fine/normal and he prescribed Iron syrup but still my son is suffering while taking breath (very minor) not always some times

As I close observer I think cough is blocked in side
