Headaches are one of the most common health complaints among Canadians. Almost everyone experiences a headache at some point in their life. However, not all headaches are the same — they vary widely in their causes, location, intensity, and how long they last. This article explains the main types of headaches, what triggers them, and how they are treated.
What Causes Headaches?
Headaches can have many different causes. A sudden headache often points to an infection, cold, or fever. Conditions like sinusitis (inflammation of the sinuses), pharyngitis (throat inflammation), or an ear infection can also cause sudden head pain.
In some cases, a headache may follow a head injury. More rarely, it can be a sign of a serious medical condition. That is why it is important to pay attention to how your headache feels, where it is located, and when it started.
Types of Headache Pain
Doctors often describe headaches by the quality and location of the pain. Deep, throbbing pain is common in migraines and cluster headaches. Superficial or pressure-like pain is more typical in tension headaches.
The location also gives clues. For example, one-sided head pain often points to a migraine. Pain that is always on the same side and never changes sides may need further investigation by a neurologist.
Common Headache Triggers
Many everyday factors can trigger headaches. Knowing your personal triggers is one of the best ways to prevent them. Triggers differ from person to person, but some are very common.
Psychological Triggers
Stress, anxiety, fear, and emotional shock are well-known headache triggers. Even positive emotions like excitement or joy can sometimes bring on a headache. Practising relaxation techniques can help reduce how often these headaches occur.
Food and Drink Triggers
Certain foods and drinks are known to trigger headaches in some people. These include:
Alcohol, especially red wine, beer, and champagne
Chocolate and cocoa products
Aged cheeses and fermented dairy products
Smoked meats and processed foods
Citrus fruits and bananas
Foods high in fat or with added preservatives
Nuts
Skipping meals, fasting, or eating irregularly can also bring on a headache. Low blood sugar (hypoglycaemia) is a common but overlooked trigger. Therefore, keeping a regular meal schedule can make a real difference.
Hormonal and Environmental Triggers
Hormonal changes are a major trigger for many women. Menstruation, oral contraceptives, menopause, and hormone therapy can all affect headache frequency. In addition, sensory triggers like bright lights, loud noise, strong smells, and vibration are common culprits.
Weather changes can also play a role. Cold or warm winds, storms, and high humidity are examples of climate-related triggers. Other factors include poor sleep, overexertion, high altitude, and certain medications that widen blood vessels.
Headaches: Common Types Explained
Migraine
Migraine is the most well-known type of vascular headache. It affects roughly 10% of people worldwide. A migraine typically causes moderate to severe throbbing pain, usually on one side of the head. Episodes last between 4 and 72 hours.
Migraines can come with nausea, vomiting, and sensitivity to light or sound. Some people experience an “aura” before the headache begins. An aura may include visual disturbances, numbness, or difficulty speaking. You can read more about migraines on the Mayo Clinic’s migraine information page.
Hypertension Headaches
High blood pressure can cause a specific type of headache. It typically appears in the morning, right after waking up. The pain tends to sit at the back of the head (occipital region) and feels like pressure or tightness. It usually eases as the morning goes on.
This type of headache is sometimes accompanied by mild nausea or dizziness. If you wake up with a headache regularly, it is worth having your blood pressure checked. Your family doctor or a local walk-in clinic can do this quickly and easily.
Cluster Headaches
Cluster headaches are less common but extremely painful. They cause intense, one-sided pain around one eye or temple. This pain often comes with a red or watery eye, nasal congestion, or a drooping eyelid on the same side.
These headaches tend to wake people from sleep at night. They strike in “clusters” — meaning several headaches occur over days or weeks, followed by a pain-free period. Cluster headaches require medical assessment and should not be self-treated.
Cervicogenic Headaches (From Neck Problems)
Cervical spondylosis, a type of wear-and-tear arthritis of the neck, can cause headaches. The pain typically starts at the back of the head or neck and may spread toward the forehead and eyes. It is usually one-sided and can feel like a deep drilling or burning sensation.
This type of headache often gets worse after sitting still for a long time. It may also be triggered by neck movements or changes in the weather. Accompanying symptoms can include vision changes, balance problems, tingling, and difficulty concentrating. Furthermore, the pain may radiate down into the shoulder and arm.
Treatment options include local heat application, physiotherapy, massage, and non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen. Always speak to your doctor before starting any new medication.
Migraine Treatment Options
Managing migraines usually involves a combination of lifestyle changes and medication. The right approach depends on how often you get migraines and how severe they are. According to Health Canada, working with your healthcare provider is essential for building an effective treatment plan.
Lifestyle Changes
Certain dietary adjustments can help reduce migraine frequency. It is wise to limit foods high in amines, such as aged cheeses, processed meats, citrus fruits, cocoa, and alcohol. Avoiding tobacco is also strongly recommended.
Stress management plays a big role as well. Relaxation techniques such as deep breathing, yoga, and biofeedback (a technique where you learn to control your body’s responses) can help. Maintaining a consistent sleep schedule is also important for preventing migraines.
Medications for Migraine
There are two main categories of migraine medication. The first is preventive medication, taken daily to reduce how often migraines occur. The second is acute medication, taken when a migraine starts to stop it in its tracks.
Common acute treatments include pain relievers like acetaminophen or ibuprofen, as well as prescription medications. Your doctor can help you find the right option for your situation. Do not take pain relievers more than 10 days per month, as overuse can actually cause more headaches — this is known as medication overuse headache.
When to See a Doctor About Headaches
Most headaches are not dangerous and can be managed at home. However, some headache patterns need prompt medical attention. If you are unsure, your family doctor is always a good first step. Walk-in clinics across Canada are also a convenient option for assessment without a wait for an appointment.
See a doctor right away or go to the nearest emergency department if you experience any of the following:
A sudden, extremely severe headache — sometimes described as a “thunderclap” or the worst headache of your life
A headache that starts after age 40 with no previous history
Headache with repeated vomiting
Headache that worsens with physical activity, coughing, or straining
A headache that has clearly changed in character or intensity
Migraine with aura lasting longer than one hour
Cluster headaches that do not respond to treatment
Headache after a head injury
Headache with fever, stiff neck, confusion, or vision changes
A neurologist may be needed for complex or ongoing headache conditions. Your family doctor can refer you through your provincial health plan if specialist care is required. The World Health Organization notes that headache disorders are among the most common nervous system disorders globally, yet they remain undertreated.
Hospitalisation may be needed in rare cases. These include a severe migraine lasting more than 72 hours, a migraine that triggers a seizure, or a stroke linked to migraine activity. These situations require immediate emergency care.
Frequently Asked Questions About Headaches
What are the most common causes of headaches?
Headaches are most commonly caused by tension, stress, dehydration, poor sleep, or illness such as a cold or sinus infection. Food triggers, hormonal changes, and environmental factors like bright light or strong smells can also bring on headaches. If your headaches are frequent or severe, speak with your family doctor.
How do I know if my headache is a migraine?
Migraines typically cause moderate to severe throbbing pain, usually on one side of the head, lasting between 4 and 72 hours. They are often accompanied by nausea, sensitivity to light or sound, and sometimes visual disturbances called an aura. If you suspect your headaches are migraines, a family doctor or neurologist can confirm the diagnosis.
When should I be worried about a headache?
You should seek immediate medical attention if you experience a sudden, extremely severe headache, a headache after a head injury, or a headache combined with fever, stiff neck, confusion, or vision changes. Headaches that are progressively getting worse or have changed in pattern also warrant a visit to your doctor or walk-in clinic. It is always better to get checked than to wait.
Can high blood pressure cause headaches?
Yes, high blood pressure can cause headaches, typically felt at the back of the head upon waking in the morning. This type of headache usually eases as the day progresses. If you regularly wake up with a headache, it is a good idea to have your blood pressure checked at a walk-in clinic or by your family doctor.
What foods trigger headaches?
Common food triggers for headaches include red wine and other alcohol, chocolate, aged cheeses, smoked or processed meats, citrus fruits, and foods high in fat. Skipping meals or eating irregularly can also bring on headaches due to drops in blood sugar. Keeping a food diary can help you identify your personal triggers.
Are headaches covered under provincial health plans in Canada?
Yes, visits to your family doctor or a walk-in clinic for headaches are covered under provincial health insurance plans across Canada. If your doctor refers you to a neurologist or orders imaging tests, those services are typically covered as well. Prescription medications may require additional coverage through a private or workplace drug plan.
