Sinus infections, or sinusitis, vary in duration depending on the type:
- Acute sinus infections typically last from about 7 to 10 days, but can extend up to 4 weeks. Most acute cases resolve on their own or with home treatment, though some may require medication if symptoms persist beyond 10 days
- Subacute sinus infections last longer, generally between 4 and 8 weeks, with symptoms continuing even with medical care
- Chronic sinus infections persist for 12 weeks (3 months) or more. These infections may last for months or even years, often requiring more advanced treatment. Symptoms may improve over time but often do not fully resolve without medical intervention
In summary, a typical sinus infection lasts about 1 to 4 weeks if acute, but if symptoms persist beyond 8 to 12 weeks, it may be classified as chronic sinusitis, which requires medical evaluation and treatment
