Some patients are often exposed to irritating substances or odors, and the causes of the condition vary from person to person. After the onset of the disease, it is recommended to visit the ENT department, where routine blood tests can be done to help determine whether there is an acute bacterial or viral inflammation. In vitro allergen testing is also required to help identify the presence of specific allergens. If allergens are present, it is necessary to avoid contact with them in daily life. Overall, the diagnosis can be clarified through standardized examination combined with the clinical experience of the doctor. After the diagnosis is clear, targeted treatment can be carried out, and regular review is needed to observe the effect.
