What symptom is least likely associated with a diagnosis of allergic rhinitis?

The symptom that is least likely associated with a diagnosis of allergic rhinitis is painful sinuses. Allergic rhinitis, commonly known as hay fever, primarily presents with symptoms related to nasal passages and eyes due to the body's response to allergens. Common symptoms include nasal congestion, clear mucus discharge, and itchy eyes, all of which stem from inflammation and irritation in the nasal mucosa and conjunctiva.

Painful sinuses, on the other hand, are more typically associated with sinusitis, which is an infection or inflammation of the sinuses that can occur as a complication following allergic rhinitis but is not a direct symptom of it. While people with allergic rhinitis can experience sinus discomfort secondary to congestion, it does not manifest as ‘painful sinuses’ as a primary symptom. Therefore, this makes it the least likely symptom to be directly linked to allergic rhinitis itself.
