How long does a sinus infection last?
Sinus infections can last several days. Viral sinus infections are usually most severe three to six days after they start, and then begin to improve by day 10. A viral sinus infection can develop into a bacterial infection, which typically lasts longer than 10 days. Patients will usually respond to antibiotics within two to three days after a bacterial sinus infection is diagnosed and treated. After that, sinus infections can resolve anywhere between seven and 14 days.
There are three types of sinusitis. All three are based on length of symptoms:
- Acute Sinusitis - symptoms last for less than four weeks
- Subacute Sinusitis - symptoms last for four to 12 weeks
- Chronic Sinusitis - symptoms last for more than 12 weeks
