  • What exactly is chronic sinusitis?
    MedlinePlusMay 2026

    Chronic sinusitis means your sinuses stay inflamed and swollen for more than 12 weeks, sometimes lasting months or years. Your sinuses are air spaces in the bones around your nose that normally make mucus to keep your nose healthy.

  • Why do my sinuses get blocked and cause pain?
    MedlinePlusMay 2026

    When your nose swells up, it blocks the sinuses and stops mucus from draining properly, which causes pain and pressure. This swelling can happen from infections, allergies, or other problems.

  • How does chronic sinusitis differ from acute sinusitis?
    MedlinePlusMay 2026

    Acute sinusitis lasts up to 4 weeks and often starts as a cold, while chronic sinusitis lasts more than 12 weeks and can continue for months or years. Chronic sinusitis is longer-lasting and harder to treat.

  • Can allergies make my chronic sinusitis worse?
    MedlinePlusMay 2026

    Yes, allergies can cause or make chronic sinusitis worse by making your nose and sinuses swell. If you have allergies, treating them may help improve your sinusitis.

  • Are there any long-term effects of not treating chronic sinusitis?
    MedlinePlusMay 2026

    Untreated chronic sinusitis can lead to complications like infections spreading to nearby areas, bone problems, or vision issues in rare cases. It's important to get treatment to prevent these problems.
