I have a sinus infection. How long can a sinus infection last?
1 Answer
It depends on whether it is acute or chronic. Acute sinusitis can last approximately 4 weeks but usually clears up in 2 weeks; and chronic sinusitis can last approximately 12 weeks. If it lasts longer than 2 weeks you should see your doctor about getting on an antibiotic.
