Upper airways: Problem, as your nasal passages or your sinuses, could be congestion or inflammation of any sort, including allergy, you need to consult an allergist/ENT doctor, goodluck

Popping : these sounds can happen when collapsed alveoli I late with inspiration. It can be without significant pathology being present
