What clinical sign can be present in patients with chronic sinusitis?

Facial pain or pressure is a common clinical sign of chronic sinusitis due to the inflammation and blockage of the sinus cavities. When the sinuses become inflamed, they can create increased pressure in the areas surrounding the sinuses, which often leads to a sensation of pain, discomfort, or a feeling of fullness in the face. This pain can be localized to specific areas, such as the forehead, cheeks, or around the eyes, depending on which sinuses are affected.

Chronic sinusitis can also be associated with other symptoms, such as nasal congestion, reduced sense of smell, and post-nasal drip, but the defining symptom related to the inflammation and pressure in the sinuses is indeed the facial pain or pressure.

Other options, while they may occur in various contexts, are not typical or direct signs of chronic sinusitis. For example, ringing in the ears may relate to different auditory issues, swollen lymph nodes can indicate infection or other systemic issues, and fever is often seen in acute sinusitis or infections but is less common in chronic cases.
