Which condition is primarily characterized by facial pain and pressure?

Sinusitis is primarily characterized by facial pain and pressure due to the inflammation of the sinus cavities, which can lead to an accumulation of mucus and swelling of the sinus linings. This inflammation can create a feeling of fullness or pressure in the face, particularly around the cheeks, forehead, and behind the eyes. Individuals with sinusitis frequently report not just pain, but also tenderness when the affected areas are touched, which further accentuates the discomfort associated with this condition.

The other options, while they may produce some overlap in symptoms, do not primarily emphasize facial pain and pressure to the same extent as sinusitis does. Allergic rhinitis often leads to nasal congestion and sneezing, chronic headaches can result from various underlying factors unrelated to sinus pressure, and nasal obstruction typically involves difficulty breathing through the nose but does not invariably cause the facial pain and pressure specific to sinus inflammation. This distinction helps to clarify why sinusitis is the most fitting choice for the condition characterized by facial pain and pressure.
