What are common symptoms of sinusitis?

Sinusitis, also known as a sinus infection, commonly presents with inflammation of the sinus cavities, which leads to nasal congestion. This inflammation often results in swelling of the nasal passages, making it difficult to breathe through the nose. Patients typically experience symptoms such as pressure or pain around the face, particularly in the forehead and cheeks, as well as thick nasal discharge that can be yellow or green in color. The congestion and inflammation are direct consequences of the infection or allergenic response involving the mucous membranes of the sinuses. Thus, understanding that inflammation and nasal congestion are hallmark symptoms of sinusitis is crucial for recognizing and treating this condition effectively.
