Can a Headache Cause a Fever?

A headache itself does not cause a fever. However, a headache can be a symptom of an underlying condition that also causes a fever. For example:

  • Infections: Various infections, such as the flu (influenza), common cold, sinusitis, and bacterial infections like strep throat or urinary tract infections, can cause both headaches and fevers.
  • Meningitis: Meningitis is an inflammation of the membranes surrounding the brain and spinal cord. It often presents with symptoms like severe headache, fever, and neck stiffness.
  • Viral Illnesses: Some viral illnesses, including certain types of viral encephalitis, can lead to headaches and fevers.
  • Inflammatory Conditions: Certain inflammatory conditions, such as temporal arteritis, can cause headaches and fever.

It’s important to note that while headaches and fever can co-occur, they are usually part of a broader set of symptoms associated with an underlying condition. If you or someone you know experiences a persistent headache along with a fever, especially if there are other concerning symptoms like neck stiffness, rash, confusion, or difficulty with coordination, it is important to seek medical attention promptly. A healthcare professional can help diagnose the underlying cause and recommend appropriate treatment.
