Can Sinus Cause Fever?


Yes, sinusitis, which is an inflammation or infection of the sinuses, can sometimes cause a fever. Sinusitis occurs when the hollow spaces around the nasal passages become blocked and filled with mucus, leading to a buildup of bacteria and viruses. This can result in symptoms such as:

  • Facial pain or pressure, particularly around the cheeks, eyes, and forehead
  • Nasal congestion and discharge
  • Coughing
  • Fatigue
  • Sore throat
  • Headache
  • Fever (in some cases)

The presence of fever in sinusitis typically suggests that the condition is more severe and may involve a bacterial infection. Bacterial sinusitis can lead to a higher body temperature, whereas viral sinusitis may not always cause a fever or may lead to a low-grade fever.

It’s important to note that while fever can be a symptom of sinusitis, it is not always present, and the severity and duration of the fever can vary. If you suspect you have sinusitis and are experiencing a fever along with other symptoms, it’s advisable to consult a healthcare provider for a proper diagnosis and treatment. In many cases, bacterial sinusitis may require antibiotics, while viral sinusitis can often be managed with rest, hydration, and over-the-counter treatments to alleviate symptoms.
