Can a nose that is too narrow cause difficulty in breathing? My 6-year-old daughter has trouble breathing through her nose when she is breathing heavily
You need to take her to a pediatric ENT surgeon to get nasopharyngoscopy and be examined. She may have obstruction of her nose in any of various locations or even a mass inside her nose. Large adenoids can also obstruct air flow. Please have her nose and face examined as soon as possible.
