CNN Health | The Latest News and Highlights:September 16, 2018 06:10:37In the US, the average headache lasts 4 to 6 weeks.
In many places, including the UK, a headache may only be noticed by a doctor if it is accompanied by fever, chills, or a high fever.
The CDC reports that the flu is one of the top causes of headache in the US.
In other words, the longer you have a headache, the more likely it is to be linked to flu.
But it’s the flu itself that can actually cause the headache.
When a person is sick, they may not be able to feel their headache.
So the symptoms can be confusing.
If the symptoms are too much to take in, it’s called a headache.
If you’re having a headache and have a fever, your body may not have enough oxygen to process it, and your body will not be working as hard as it should.
So your body can’t produce as much energy as it normally does to fight the flu.
This causes your body to produce less of a headache than it normally would.
A headache can be caused by:Antibiotics: This can cause a buildup of bacteria in the bloodstream that can cause inflammation.
This can lead to blood clots and other infections.
The more blood clotted, the higher the risk of a stroke or heart attack.
Other medications: Drugs called antihistamines can cause your blood pressure to rise, and can cause severe stomach pain.
This may lead to stomach cramps, vomiting, or diarrhea.
These symptoms can also be caused, in part, by the medications.
Treatment for a headache:Antiviral medication: Antihistamines and other drugs can slow down the flu virus, but not all of them are 100 percent effective.
If you need medication, call your doctor first.
If your headache has worsened, call 911.
