Hi my son is 7yr old. He is a mouth breather. He doesn't have any infection... But breathes thru mouth. Earlier he doesn't get cold cough often. But now he gets cold cough often. Tried nasal sprays but still he continues mouth breathing... Now using physiomer nasal spray. Can u plz help us in letting know should v go for surgery or how long to wait for adenoids to shrink on its own? Will this affect his growth both physically and mentally? Pl help.. Thank you Dr.
