You know the drill. Your forehead feels like it was hit with a hammer and your eyes are throbbing. The pain pulsates through your neck and leaves your shoulders feeling tight. You can't think. You can't focus. Dim the lights, shut off the television, and cancel your plans. You have a headache.
Headaches are, unfortunately, a normal part of life . Some people just deal with the pain while others wonder if there is a more serious cause behind their discomfort. Most of the time, a headache is simply a nuisance. But there are instances where a serious medical condition is the culprit behind the pain.
Common characteristics of a headache
If you're experiencing a headache, it can likely be described by:
- Pain that resembles pressure: This can be mild to excruciating
- Pain that affects the front, top, or sides of your head
- Pain behind your eyes
- Difficulty concentrating
More serious headache symptoms
Symptoms of more severe headaches or migraines include:
Infection and illness
Headaches may be due to the following illnesses.
- Norovirus: What did you have for lunch? We're only asking because norovirus is a form of food poisoning that can cause severe vomiting and diarrhea. Headaches are also a common symptom, most likely being a side effect of dehydration .
- Common cold: Cough. Sneeze. Repeat. If you have a cold, headaches are a common symptom, thanks to the swelling in the sinus cavities .
- Influenza: We all try to escape flu season unscathed but for those of us who do end up down for the count, headaches are a common symptom. Fever is also common in those with a flu virus . As a result, blood vessels dilate and pressure inside the head increases.
You may be experiencing headaches due to one of the following conditions.
- Migraine: Nearly 12 percent of the American population deals with migraine headaches but despite this proportion, the cause is considered unknown . Some can feel a migraine attack coming on when exposed to certain foods or smells while others have no warning at all. The pain can last for hours or even days.
- Tension: Tension headaches are probably the most common type of headache . These are the ones that creep up in the middle of your work day and make each minute feel like an hour.
10 Possible Headache Conditions
The list below shows results from the use of our quiz by Buoy users who experienced headache. This list does not constitute medical advice and may not accurately represent what you have.
New, or new-onset, migraine means the person has never experienced a migraine headache before. A migraine is a one-sided headache that causes intense pain and throbbing due to blood vessels dilating in the brain.
The exact reason for new-onset migraine headache is not known, but a number of causes are being studied:
- Soy isoflavone supplements, especially in men.
- Use and overuse of certain medications.
- Traumatic head injury.
- Angioma, which is a cluster of dilated blood vessels in the brain.
- A complication of surgery for some heart conditions.
Anyone with a sudden severe headache should be seen by a medical provider, so that a more serious cause can be ruled out. A transient ischemic attack, also known as TIA or mini-stroke, can have symptoms similar to a migraine but is far more serious.
Diagnosis is made through patient history, physical examination, and imaging such as a CT scan.
Treatment for migraine varies with the individual. Lifestyle changes may be recommended and there are a number of medications that may be tried.
Top Symptoms: new headache, fatigue, nausea, mild headache, headache that worsens when head moves
Symptoms that always occur with new migraine: new headache
Symptoms that never occur with new migraine: fever, diarrhea, productive cough, headache resulting from a head injury
Tension headache (first onset)
Tension-type headaches are the most common type of headache. It is pain or discomfort in the head and/or neck. It's often associated with muscle tightness in these areas. This condition can occur as little as once a year (infrequent) but as often as more than 15 days per month (chronic). The cause of tension-type headaches is not clear.
Top Symptoms: new headache, nausea or vomiting, moderate headache, loss of appetite, mild headache
Symptoms that always occur with tension headache (first onset): new headache
Symptoms that never occur with tension headache (first onset): photo and phonophobia, throbbing headache, headache resulting from a head injury
A cluster headache is a type of recurring headache that is moderate to severe in intensity. It is often one-sided head pain that may involve tearing of the eyes and a stuffy nose. Attacks can occur regularly for 1 week and up to 1 year. Each period of attacks (i.e. each cluster) is separated by pain-free periods that last at least 1 month or longer. Other common headaches may also occur during these cluster-free periods.
Top Symptoms: severe headache, nausea, throbbing headache, history of headaches, sensitivity to light
Symptoms that always occur with cluster headache: severe headache
Urgency: Hospital emergency room
Acute bacterial sinusitis
Acute bacterial sinusitis, also called bacterial rhinosinusitis or "sinus infection," has symptoms much like viral rhinosinusitis but a different treatment.
Any sinusitis usually begins with common cold viruses. Sometimes a secondary bacterial infection takes hold. Like cold viruses, these bacteria can be inhaled after an infected person coughs or sneezes.
Anyone with viral sinusitis, upper-respiratory allergy, nasal passage abnormality, lung illness, or a weakened immune system is more prone to bacterial sinusitis.
Symptoms include thick yellowish or greenish nasal discharge; one-sided pain in the upper jaw or teeth; one-sided sinus pain and pressure; fatigue; fever; and symptoms that get worse after first improving.
See a doctor right away for severe headache, high fever, stiff neck, or vision changes. These can indicate a medical emergency.
Diagnosis is made with a simple examination in the doctor's office.
Bacterial sinusitis can be treated with antibiotics, but this is not always necessary. Often rest, fluids, and over-the-counter pain relievers and decongestants are enough.
Prevention is done through good lifestyle and hygiene to keep the immune system strong.
Top Symptoms: fatigue, headache, cough, sinusitis symptoms, muscle aches
Symptoms that always occur with acute bacterial sinusitis: sinusitis symptoms
Symptoms that never occur with acute bacterial sinusitis: clear runny nose, being severely ill
Urgency: Primary care doctor
The common cold is a viral infection of the upper respiratory tract, which includes the nose, mouth, sinuses, throat, and larynx. There are over 200 viruses that can cause upper respiratory infections, and usually the exact virus behind a cold is never known.
The common cold is, of course, very common...
Insomnia disorder is a short-term or chronic condition whereby individuals have difficulty
sleeping. Other common symptoms include fatigue, difficulty with concentration, social
dysfunction, reduced motivation, and behavioral changes. The short-term form of
the condition is usually ...
Sinus headache, also called sinusitis or rhinosinusitis, is caused by either a bacterial or a viral infection of the sinuses (open spaces) behind the eyes and nose.
Symptoms include fever; thick nasal discharge which may be clear, white, greenish or yellowish; some loss of sense of smell; foul-smelling breath; and pain, congestion, and pressure over the sinus areas of the face, especially if bending forward or lying down.
A self-diagnosed "sinus headache" very often turns out to be a migraine headache with a few sinus symptoms. This requires very different treatment from an actual sinus headache, and is an important reason to see a medical provider about any sort of ongoing headaches.
Diagnosis is made through patient history, physical examination, and sometimes CT scan or MRI of the head to look for changes in the sinuses.
A true sinus headache, if caused by a bacterial infection, will be treated with antibiotics. If caused by a viral infection, the symptoms can be treated with over-the-counter pain relievers and alternating hot and cold compresses.
Top Symptoms: headache, headache that worsens when head moves, facial fullness or pressure, mucous dripping in the back of the throat, sinus pain
Symptoms that always occur with sinus headache: headache
Symptoms that never occur with sinus headache: fever, being severely ill, sore throat, muscle aches, cough, drooping eyelid
Brain tumor or mass
In medical terms, "mass" and "tumor" mean the same thing: the unexplained, out-of-place growth of tissue anywhere in the body, including the brain.
The cause of any sort of brain tumor is unknown. Some originate in the brain, while others spread from cancers growing in other parts of the body.
Symptoms may include increasing headaches; nausea and vomiting; blurred or double vision; loss of sensation in an arm or leg; loss of balance; confusion; speech difficulties; or seizures.
If symptoms persist, it is important to see a medical provider so that any treatment can begin as soon as possible.
Diagnosis is made through neurological examination, CT scan, and/or MRI.
If the mass or tumor is found to be benign, that means it is not cancer and not harmful. It may or may not be treated.
If it is malignant, that means it is cancer and must be treated. This will involve some combination of surgery, radiation therapy, and chemotherapy, followed by specialized therapy to help with recovery.
Top Symptoms: fatigue, headache, nausea, loss of appetite, irritability
Symptoms that always occur with brain tumor or mass: focal neurological symptoms
Urgency: In-person visit
Influenza, or "flu," is a contagious respiratory illness caused by viruses. It is spread through the air by coughing, sneezing, or even talking.
Anyone can get the flu, but those who are very young, over 65, and/or have pre-existing medical conditions are most at risk for complications.
Symptoms include fever, chills, cough, sore throat, body aches, and extreme fatigue. The symptoms may appear very suddenly.
Flu can bring on secondary bacterial infections in the lungs or ears. Dehydration is a great concern because the patient rarely wants to eat or drink.
Diagnosis is usually made by symptoms. There are tests that use a swab taken from the nose or throat, but they are not always accurate or necessary.
Treatment consists mainly of good supportive care, which means providing the patient with rest, fluids, and pain-relieving medication such as ibuprofen. Do not give aspirin to children.
Antibiotics cannot help with the flu, since antibiotics only work against bacteria. There are anti-viral medications that a doctor may prescribe.
The best prevention is an annual flu shot.
Top Symptoms: fatigue, headache, loss of appetite, cough, muscle aches
Symptoms that never occur with influenza: headache resulting from a head injury
Urgency: Phone call or in-person visit
Concussion not needing imaging
A traumatic brain injury (TBI), or concussion, happens when a bump, blow, jolt, or other head injury causes damage to the brain. Every year, millions of people in the U.S. suffer brain injuries. More than half are bad enough that people must go to the hospital, and the worst injuries can lead to permanent brain damage or death.
Top Symptoms: dizziness, irritability, depressed mood, difficulty concentrating, trouble sleeping
Symptoms that always occur with concussion not needing imaging: head or face injury
Symptoms that never occur with concussion not needing imaging: recent fall from 6 feet or higher, severe vomiting, posttraumatic amnesia over 30 minutes, slurred speech, fainting, moderate vomiting
Urgency: Primary care doctor
Headache Treatments and Relief
In most cases, the best way to treat a headache is to distract yourself from the discomfort or rest until you feel better.
When headaches are an emergency
If you are experiencing any of the following headache symptoms, seek medical attention immediately.
- You're having the worst headache you've ever had
- You're experiencing vision loss that doesn't improve
- You lose consciousness
- You're vomiting uncontrollably
- Your headache has lasted more than 72 hours with minimal relief
- You have a headache with any symptoms of weakness in the arms, legs or trouble speaking: This could be a stroke.
At-home headache treatments
For run-of-the-mill headache symptoms, consider any of the following treatments.
- Over-the-counter medication: A quick dose of acetaminophen, aspirin, ibuprofen, or naproxen should provide you with quick relief.
- Coffee: Pour yourself a hot cup of joe. If you regularly drink caffeine but skipped your morning beverage, a dose of caffeine should help.
- Massage: We're giving you an excuse to book a spa treatment. If that's not an option, massaging your own neck, head, or shoulders can help alleviate pain from mild headaches.
- Rest: If your headache is a result of an illness, like the flu or a cold, rest is some of the best medicine. Choose a comfortable location in a dark room with minimal noise.
- Exercise: Though it might seem like exercise would make your headache worse, a quick bike ride, dip in the pool, or brisk walk through the neighborhood can help reduce your discomfort.
- Essential oils: Both lavender and peppermint have been used to naturally treat headaches. You can either massage the oils (after being mixed with a carrier oil) over your temples or diffuse them.
- Water: If you have to think about the last time you had a glass of water, early dehydration could be the cause of your headache. Increase your water intake and you'll hopefully notice a decrease in pain rather quickly.
FAQs About Headache
Here are some frequently asked questions about headache.
Why do I have a constant headache?
Headaches can be caused by many different things, including chronic migraine headaches, chronic tension headaches, and a consistent headache called "hemicrania continua" . Usually, these headaches occur frequently and last longer than four hours at a time. If you are having one of these headaches commonly, this is called a "Chronic Daily Headache." Most commonly, it is caused by a change in diet, sleep, or stress but can also me caused by head trauma, drugs, or dehydration.
What is cluster headache?
A cluster headache is a headache that normally affects one side of the face and is accompanied by severe pain around or above the eye, and at the temple (the upper frontal side of the head). It may also occur with droopy eyelids, crying, redness in the eye, and usually lasts 15 minutes to three hours . Attacks may occur as frequently as eight times a day for weeks.
What does a migraine feel like?
A migraine may feel different for different people, but it is most commonly described as a one-sided throbbing headache accompanied by sensitivity to light and sound as well as occasional nausea. It may also be accompanied by floating figures or "aura" within an individual's field of vision. Often, it is improved by rest in a quiet space and can be prevented by adequate hydration and adequate sleep without major changes in consistency.
What are the common causes of headaches?
Headaches are commonly caused by lack of sleep, dehydration, change in diet, and stress as well as more worrisome causes like head trauma. Tension headaches are the most common headaches and can be an early sign of a cold or can be caused by disrupted sleep or just psychological stress. To determine the cause of your headache, you should write down any accompanying symptoms including nasal congestion, tearing in the eye, redness in the eye, sore throat, neck or back pain, as well as the side of the head on which a headache occurs and the quality of the pain. The pain may be dull or sharp, pulsatile or constant, it may be caused by a particular motion or food item. All of these are important pieces of information to determine the cause of a headache.
