6 yo boy every morning and before sleep are throat clearing. no other symptoms( no runny nose, no cough). sometime he snore. sometime we hear at night how he swallow saliva, and then he may cough. very happy, vocal and noisy playful boy. what is it?

Upper airway: There may be congestion in the nasal passages and post nasal drip. A virtual consultation is available to review his findings. Snoring may indicate a sleep disorder if present consistently. Use nasal saline rinses twice daily, in the morning and evening, and discuss nasal steroid spray with your pediatrician. Avoid dust, pollen, mold and other allergens. Avoid smoke exposure and keep bedroom clean
