Sinus infections often follow a cold and cause pain and pressure in your head and face. Sinusitis can be either acute (sudden) or chronic (long-term). With chronic sinusitis, the infection or inflammation does not completely go away for 12 weeks or more.
Sinusitis that lasts 12 weeks or longer is called chronic sinusitis. It is more difficult to treat and responds more slowly to antibiotics than acute sinusitis. Antibiotic therapy is usually recommended for chronic sinusitis and may require a longer course of treatment.
