A blocked nose can last anywhere from a few days to several weeks, depending on the underlying cause.
Causes of a Blocked Nose
A blocked nose can be caused by a variety of factors, such as colds, allergies, sinus infections, and even structural issues.
Colds: Colds are caused by a virus and can cause a blocked nose for up to 10 days. Colds are usually accompanied by other symptoms, such as a sore throat, cough, and fever.
Allergies: Allergies can cause a blocked nose due to inflammation of the nasal passages. Allergies can last for days or weeks, depending on the severity of the reaction and the individual's sensitivity to the allergen.
Sinus infections: A sinus infection can also cause a blocked nose. This type of infection usually lasts for 7 to 10 days and is usually accompanied by other symptoms, such as facial pain, a fever, and a thick, yellow-green mucus.
Structural issues: Structural issues, such as a deviated septum or nasal polyps, can also cause a blocked nose. In these cases, the blocked nose may last for weeks or months until the underlying issue is treated.
Treating a Blocked Nose
Treating a blocked nose depends on the underlying cause. Over-the-counter medications such as decongestants, antihistamines, and nasal sprays may help reduce symptoms. A doctor may also recommend a nasal steroid spray or oral antibiotics for a sinus infection. In cases of structural issues, surgery may be needed to correct the problem.
