Headaches are one of the most common pain-related health problems in both children and adults. You may have a headache along with another minor health problem such as a sore throat, cold, or sinus problem.
Types of headaches
The most common types of headaches usually are not serious but may occur again and again.
- Tension headaches are the most common type of headache and are often caused by stress and emotional strain. Most adults have tension headaches from time to time, and everyone may have different areas of pain.
- Cluster headaches
- Migraine headaches. Approximately one-third of people who have migraine headaches first began having them as teenagers.
Common causes of headaches
Common causes of headaches include:
- Alcohol, caffeine, or other drug use or withdrawal.
- Changes in the levels of chemicals in the body (neurotransmitters).
- Coughing or sneezing.
- Dental problems or procedures, such as pain from grinding the teeth or from a root canal.
- Eating or drinking cold foods and fluids.
- Emotional stress.
- Exposure to smoke or fumes from chemicals, including carbon monoxide.
- Eye strain.
- High altitude. Lower oxygen levels at high altitudes can cause headaches.
- High blood pressure (hypertension).

- Medical procedures, such as the aftereffects of a lumbar puncture (spinal tap).
- Medicines. Many medicines can cause headaches.
- Muscle strain in the neck, upper back, or shoulder muscles.

- Premenstrual syndrome (PMS).
Headaches with other serious symptoms
Although rare, a headache may be a symptom of a serious illness. Other symptoms, such as vomiting, dizziness, or changes in vision, may also be present. The following serious illnesses or injuries can cause headaches.
- A head injury:
- Injury to the brain (concussion)
- Fracture of the skull
- Bleeding in or around the brain
- Brain tumour, which causes swelling within the brain
- Infection in the brain (encephalitis) or of the membrane surrounding the brain and spinal cord (meningitis)
- Stroke, a problem that occurs when a blood vessel (artery) that supplies blood to the brain bursts or is blocked by a blood clot
- A rupture of a blood vessel with bleeding in or around the brain (aneurysm)
Check your symptoms to decide if and when you should see a doctor.
Check Your Symptoms
Many things can affect how your body responds to a symptom and what kind of care you may need. These include:
- Your age. Babies and older adults tend to get sicker quicker.
- Your overall health. If you have a condition such as diabetes, HIV, cancer, or heart disease, you may need to pay closer attention to certain symptoms and seek care sooner.
- Medicines you take. Certain medicines and natural health products can cause symptoms or make them worse.
- Recent health events, such as surgery or injury. These kinds of events can cause symptoms afterwards or make them more serious.
- Your health habits and lifestyle, such as eating and exercise habits, smoking, alcohol or drug use, sexual history, and travel.

- Call your doctor if symptoms get worse or you have any concerns (for example, if symptoms are not getting better as you would expect). You may need care sooner.
Neurological Symptoms (Loss of Function)
Neurological symptoms—which may be signs of a problem with the nervous system—can affect many body functions. Symptoms may include:

Pain Severity, Adult or Child (Not Baby)
Pain in adults and older children

- Moderate pain (5 to 7): The pain is bad enough to disrupt your normal activities and your sleep, but you can tolerate it for hours or days. Moderate can also mean pain that comes and goes even if it's severe when it's there.

Most of the time headaches get better or go away with home treatment and do not require a visit to a doctor. Home treatment for headaches can often help reduce the severity of pain and the length of time the pain is present. Home treatment may also relieve other symptoms, such as fever, nausea or vomiting, anxiety, or muscle aches. Start home treatment as soon as you can. Be sure to review the home treatment information for any other symptoms you may have.
If your doctor has prescribed a specific treatment for your headaches, begin treatment as soon as a headache starts. Be sure to follow his or her instructions when taking any prescription medicine for your headache.
For mild pain without other symptoms, try the following:
- Rest in a quiet, dark room.
- Place a cool compress on your forehead.
- Do not smoke, drink alcohol, or use illegal drugs.
|Try a non-prescription medicine to help treat your fever or pain:|
Talk to your child's doctor before switching back and forth between doses of acetaminophen and ibuprofen. When you switch between two medicines, there is a chance your child will get too much medicine.
|Be sure to follow these safety tips when you use a non-prescription medicine:|
You may be able to reduce the frequency and severity of your headaches by trying:
- Relaxation exercises. These exercises can help take away tension and stress that cause headaches or make them worse.
- Heat, such as hot water bottles, heating pads, or hot baths, to relax tense muscles. Be careful not to burn yourself.
- Ice, such as an ice pack applied to the back or the neck or the temples.
- Massage therapy, biofeedback, and other complementary medicine treatments can reduce muscle tension, especially in your neck and shoulder muscles. Muscle tension can cause headaches or make them worse.
Headaches in children
When your child has headaches:
- Talk to your child. Let him or her know you care. Extra attention and quiet time may be all that is needed to relieve the pain.
- If your child's doctor has prescribed a specific treatment for his or her headaches, begin treatment as soon as your child complains of the pain.
- Let your child rest quietly in a darkened room with a cool compress on his or her forehead.
- If your child's headache pain is mild, encourage him or her to go on with normal activities.
- Let your child do his or her usual activities if he or she feels like it unless the headache pain is moderate to severe.

Symptoms to watch for during home treatment
Call your doctor if any of the following occur during home treatment:
- Pain increases or other symptoms develop, such as fever, confusion, vision changes, or vomiting.
- Symptoms become more severe or frequent.
- Eat regularly. Do not skip meals. Choose nutritious foods. Do not fill up on salty foods or carbonated beverages.
- Keep a regular sleep schedule. Set a bedtime and time to get up, and stick to them, even on weekends. This will help your body get used to a regular sleep time. Avoid oversleeping.
- Physiotherapy may
help you strengthen your neck muscles, improve your posture, and increase your
- Exercise regularly. Walking, cycling, jogging, swimming, or even dancing or gardening are great ways to relieve stress. If you tend to hold tension in your neck and shoulders, walking may be especially helpful. The swinging motion of the arms seems to relax those muscles.
- Practice a relaxation exercise once or twice a day for 10 to 20 minutes.
- Try massage, which can reduce muscle tension, especially in your neck and shoulder muscles. Muscle tension can cause headaches or make them worse.
- Practice good posture and body mechanics at home
and at work:
- Sit straight in your chair with your lower back supported. If you sit most of the day, take breaks once an hour to stretch your neck muscles. There are some specific neck exercises you can do during your breaks.
- If you work at a computer, adjust your monitor so that the top of the screen is at eye level. Use a document holder to keep the copy at the same level as the screen.
- If you frequently use the telephone, consider a headset or speaker phone. Do not cradle the handset between your shoulder and your ear.
- Have frequent dental checkups and yearly eye examinations.
Headaches can often be prevented by avoiding things that may cause, or "trigger," the pain. Although these triggers may be different for different people, generally avoid:
- Alcohol and caffeine (coffee, tea, or soda pop).
- Sudden caffeine withdrawal.
- Foods, such as very salty foods or foods that contain the preservative MSG.
- Poor eating habits, including missing meals, extreme diets, and fasting.
- Changes in usual sleep patterns, not getting enough sleep, or oversleeping.
- Stress, anxiety, or depression.
- Medicines, such as heart medicines, blood pressure medicines, and hormones.
- Poor posture and body mechanics.
- Smoking cigarettes or cigars, or breathing second-hand smoke.
- Glare from sunlight or artificial light.
- Exposure to strong odours.
- Strain in the muscles of the jaw from grinding or clenching teeth or chewing gum.
- Herbal remedies, such as ginseng or St. John's wort.
To prevent a child's headache:
