Is Persistent Headache a Symptom of the Flu?

Headaches can develop at any time, and sometimes are a symptom of an illness such as influenza (flu). Fortunately, recognizing the symptoms of flu and paying attention to when the headache began can help determine whether the persistent headache is the result of flu.

  1. Features

    • Early symptoms of flu include sneezing, runny nose and sore throat. These are accompanied by fever higher than 101, chills or sweats, headache and body aches, fatigue and loss of appetite.

    Identification

    • Doctors can collect a sputum sample and send it to a laboratory for confirmation of flu. Persistent headaches are diagnosed by physical exam and tests such as computerized tomography and magnetic resonance imaging.

    Effects

    • Persistent headaches can interfere with performing normal daily activities and getting enough sleep. Flu can make a person weak for a week or longer and can cause complications including pneumonia.

    Considerations

    • A persistent headache not accompanied by other flu symptoms might be a result of stress, poor posture, jaw grinding, hormones, vision problems, respiratory infections, or low blood sugar.

    Treatments

    • Within the first two days of symptoms, doctors can treat flu with oseltamivir or zanamivir, along with pain relievers and fluids. Persistent headaches not associated with flu might be treated with pain relievers, antidepressants or muscle relaxants.

    Prevention/Solution

    • Getting vaccinated each year for the flu can prevent flu symptoms. Frequent hand washing, coughing into your elbow, and staying home when sick can also reduce the chance of getting or spreading the flu. Stress management, good posture and massage may prevent persistent headaches from other causes.
