What is a common symptom of sinusitis?

Facial pain and pressure is a common symptom of sinusitis because the condition involves inflammation and swelling of the sinuses, which are hollow spaces within the bones surrounding the nose. This inflammation can lead to a buildup of mucus and subsequent blockage of the sinus passages, resulting in discomfort in the areas around the cheeks, forehead, and even behind the eyes. Patients often report a feeling of fullness or pressure in the face, which is reflective of the underlying inflammation and congestion occurring in the sinus cavities.

In contrast, visual disturbances, tinnitus, and loss of balance are not typically associated with sinusitis. Visual disturbances may arise from other eye-related conditions, tinnitus is often linked to ear disorders, and loss of balance can indicate issues with the vestibular system or inner ear – none of which are characteristic of sinusitis. Therefore, the specific symptoms of facial pain and pressure directly relate to the pathophysiology of sinusitis, making it the correct choice.
