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.
Acute sinusitis usually clears up within 3 weeks, or within 1 to 2 weeks with treatment. Chronic sinusitis lasts 3 to 8 weeks or longer and may require longer courses of antibiotics and other treatments to resolve the condition.
