Symptoms
Symptoms include feeling of pressure in the face (particularly starting from the area above and below the eyes and behind the nose), nausea, sore throat, bad headache, pain in the ear, accompanied by bad breath, and sometimes fever. Other symptoms may occur even after the treatment has started. These symptoms are usually an indication of the sinusitis subsiding, and they include yellow-green nasal drainage (clear or thick), lessening of pressure in the face, and relief in breathing.
