How Long Do Symptoms Last?Most people with acute viral sinusitis get better on their own within 7 to 10 days. Many cases of acute bacterial sinusitis also get better on their own or with the help of antibiotics.
If your symptoms are not getting better, or if they come back, you should see your healthcare provider again. It is possible that the antibiotic did not completely eliminate the infection. A different antibiotic or further testing may be recommended.
