Introduction
The flu is a common respiratory illness that can cause a variety of symptoms, including headache, fever, body aches, and fatigue. For many people, the headache is one of the most debilitating symptoms of the flu. But how long does the flu headache last?
How Long Does the Flu Headache Typically Last?
The length of time that a flu headache lasts can vary from person to person. However, most people find that their headache starts to improve within 24-48 hours of the onset of their other flu symptoms. By day 3-4, most people’s headaches are gone completely.
Why Does the Flu Headache Last So Long?
The flu headache is caused by inflammation of the blood vessels in the brain. This inflammation is triggered by the body’s immune response to the flu virus. As the body fights off the virus, the inflammation gradually decreases, and the headache goes away.
What Can I Do to Relieve the Flu Headache?
There are a few things that you can do to relieve the pain of a flu headache:
- Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help to reduce inflammation and pain.
- A cold compress can help to numb the pain and reduce inflammation.
- Rest is important for allowing the body to recover from the flu.
- Staying hydrated is important for preventing dehydration, which can worsen a headache.
When Should I See a Doctor?
In most cases, the flu headache is not a serious problem. However, you should see a doctor if your headache:
- Is severe and does not improve with over-the-counter pain relievers.
- Is accompanied by other symptoms, such as fever, chills, or body aches.
- Lasts for more than a few days.
