Acute sinusitis causes inflammation of the cavities that surround the nasal passages (sinuses). This hinders drainage and causes accumulation of mucus.
When you suffer from acute sinusitis, you may feel respiratory distress. It is possible that your face swells the area around your eyes and that you feel throbbing facial and head pain.
Acute sinusitis is mostly due to the common cold. Unless a bacterial infection develops, the resolution of most cases takes between a week and 10 days.
