Does Sinusitis Cause Fever?

Sinusitis itself is typically not associated with fever. Acute sinusitis, which is often caused by a viral infection, may result in symptoms such as nasal congestion, facial pain or pressure, post-nasal drip, and a runny or stuffy nose. These symptoms are usually not accompanied by a fever.

However, in some cases, sinusitis can lead to a low-grade fever, especially when it is caused by a bacterial infection. Bacterial sinusitis is less common than viral sinusitis but can be more severe. If the sinuses become infected with bacteria, the body’s immune response may include a mild increase in body temperature, resulting in a low-grade fever.

Fever is typically not a prominent or defining symptom of sinusitis, and many people with sinusitis do not experience fever. If you have sinusitis and are concerned about fever or other symptoms, it’s a good idea to consult with a healthcare professional for a proper diagnosis and appropriate treatment. They can determine the underlying cause of your symptoms and recommend the best course of action for your specific condition.
