Symptoms of sinusitis may include thick, yellow or green drainage from the nose, pain, swelling or tenderness around the cheeks, eyes, nose or forehead and nasal congestion or obstruction, according to Mayo Clinic. Patients with sinusitis may also have difficulty breathing through the nose.
Additional possible symptoms of sinusitis include ear pain, fatigue, irritability, nausea, aching in the teeth or upper jaw and a sore throat, explains Mayo Clinic. Some patients experience a reduced sense of taste and smell and bad breath, or halitosis. A cough that gets worse at night when lying down may also be present with sinusitis.
