Nasal congestion can have various causes, ranging in severity from 'troubling' to 'serious'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose nasal congestion, we could:
|General Toxicity||0%||Ruled out|
|Mercury Toxicity||0%||Ruled out|
|Vitamin Pantothenic Acid Need||0%||Ruled out|
|Milk Allergy||0%||Ruled out|
