Headache is a common symptom that almost everyone experiences at some point. Some people have only mild headaches for a few hours due to lack of sleep or stress. But others have recurrent headaches lasting many days, affecting concentration, sleep and quality of life. So what is a headache, what are the common types, and when should patients seek medical evaluation?
What is a headache?
A headache is a pain, pressure or discomfort felt in the head or face. Mechanically, headaches occur when a trigger stimulates nerves in the head, causing them to send pain signals to the brain.
According to 2021 data from the World Health Organization (WHO), headache disorders affect about 40% of the global population, with a higher prevalence in women than men. These conditions not only cause discomfort but also directly impact work performance, sleep, concentration and overall quality of life.
Common types of headaches and distinguishing symptoms
Today, medicine recognizes more than 150 different types of headaches. However, in practice patients most commonly experience the following headache types.
Migraine
Migraine commonly affects adults aged 35–45, especially women. Migraine typically causes throbbing pain on one side of the head. Attacks can last from several hours to several days and often worsen with physical activity. During a migraine, patients may be sensitive to light, sound and smells, and may experience nausea or vomiting.
Tension-type headache
Tension-type headaches (TTH) are characterized by a pressing or tightening sensation around the head, like a band wrapped around the forehead or temples. Pain can radiate to the neck or originate from the neck. This type of headache can be related to prolonged stress, sleep deprivation or neck muscle tension.
Cluster headache
Cluster headache (CH) is a primary headache disorder with very severe intensity. Cluster attacks are short-lived but can recur multiple times per day. Pain is usually centered around one eye and may be accompanied by tearing, eye redness, eyelid droop, restlessness and inability to sit still during an attack.
Cervicogenic headache
Cervicogenic headache is a headache caused by disorders of the cervical spine or surrounding soft tissues. Patients often have pain on one side of the head or face, starting from the nape and spreading to the back of the head and temples. Attacks may be accompanied by neck stiffness, neck and shoulder pain, limited neck rotation, pain radiating to the shoulder or arm, and sometimes nausea.
Sinus headache
Sinus headache is usually associated with inflammation or blockage of the facial sinuses. Patients may have pain in the forehead, cheeks or around the eyes, accompanied by nasal congestion, nasal discharge, facial heaviness or increased pain when bending forward.
Medication-overuse headache
Medication-overuse headache occurs when patients use pain relievers or headache medications for a prolonged period. Pain typically occurs many days per week, is persistent and uncomfortable, and often worse upon waking. This is why patients should avoid long-term self-medication with analgesics before identifying the cause of the headache.
Causes of Headaches
Before treatment, patients need to identify the correct cause of their headache. If the cause is misidentified, treatment can easily be misdirected. For example, a tension headache may improve with adequate sleep, stress reduction, and lifestyle adjustments. But if the headache originates from the cervical spine, simply taking painkillers or resting is often only temporary because the underlying neck issue continues to trigger pain.
Primary Headaches (Not Caused by Underlying Disease)
Primary headaches are pain conditions not caused by another medical disorder. Common types of primary headaches include migraine, tension-type headache, and cluster headaches.
Common triggers of primary headaches include:
- Chronic stress/tension
- Sleep deprivation, late nights, disrupted sleep patterns
- Side effects of certain medications, alcohol, or excessive caffeine
- Dehydration leading to reduced oxygen delivery to the brain
- Hormonal changes in women (postpartum, perimenopause, or during the menstrual cycle)
- Poor posture can increase neck and shoulder muscle tension, contributing to the onset or worsening of headaches
Secondary Headaches Due to Underlying Conditions
Secondary headaches occur when the pain originates from another disease or disorder. These causes require careful examination and diagnosis to treat effectively and reduce recurrence.
Some common causes include:
- Eye conditions such as refractive disorders, glaucoma, or prolonged eye strain can cause headaches, particularly in the forehead, eye socket, or around the eyes
- Anemia or reduced cerebral circulation: when the brain does not receive enough oxygen and nutrients, patients may experience headaches with blurred vision, dizziness, fatigue, and poor concentration
- Sinusitis: sinus inflammation commonly causes pain in the forehead, cheeks, around the eyes, or across the face
- Serious neurovascular conditions such as stroke, intracranial hemorrhage, brain tumor, or brain infection. Seek emergency care immediately if a headache begins suddenly, is severe, or is accompanied by vomiting, high fever, loss of balance, or altered consciousness.
- Trauma or cervical spine disorders such as whiplash, cervical spondylosis, cervical disc herniation, neck and shoulder muscle strain, cervical mechanical dysfunction, or cervical nerve compression can all cause headaches. When structures around the neck (especially C1–C3) are inflamed, compressed, stretched, or unstable, pain signals can radiate to the back of the head, temples, forehead, or around the eyes.
When Should You See a Doctor for a Headache?
In some cases, a headache can signal a serious condition involving the nervous system, cerebral blood vessels, infection, or trauma. Therefore, if a headache occurs with any of the following abnormal signs, the person should seek medical attention for timely evaluation, diagnosis, and treatment:
- Sudden, severe headache
- A new headache in someone over 50 years old, especially if they have rarely or never experienced similar headaches before.
- Headache in a person with a weakened immune system, such as someone with HIV, undergoing chemotherapy, or with serious underlying illnesses.
- Headache accompanied by dizziness, vomiting, confusion, or unusual mood changes.
- Headache with changes in gait, loss of balance, or difficulty coordinating movements.
- New neurological signs, such as sudden weakness in the arms or legs, facial droop, difficulty speaking, blurred vision, seizures, or altered consciousness.
- Headache after a fall, blow, or injury to the head/neck, even if symptoms initially seem mild.
Effective headache treatments
Home treatment for headaches
For mild headaches not related to a serious underlying condition, symptoms can often improve with lifestyle adjustments. Prioritize rest, stress reduction, adequate hydration, healthy nutrition, and light physical activity such as walking, stretching, or yoga.
If the headache is associated with neck and shoulder muscle tension, applying heat or cold packs or gentle massage to the temples, forehead, and neck can help soothe pain. Patients should also limit alcohol, tobacco, coffee, and stimulants if they worsen the headache.
For office workers, adjust sitting posture, place the screen at eye level, avoid prolonged downward gaze at phones, and take breaks every 45–60 minutes. However, if headaches recur frequently, worsen, or do not improve with rest, seek medical evaluation to determine the exact cause.
Using pain relievers
Some headaches respond to over-the-counter pain relievers such as paracetamol (acetaminophen), ibuprofen, or aspirin. However, patients should not use these medications long-term without a doctor's guidance. Overuse of pain relievers can make headaches persistent and may lead to medication-overuse headache.
Especially for headaches related to the cervical spine, pain relievers only control the symptom of pain and cannot treat joint dysfunction, neck and shoulder muscles, intervertebral discs, or cervical nerve disorders.
Chiropractic spinal adjustment therapy
Chiropractic adjustment is a non-drug, non-invasive treatment approach focused on correcting misalignments and nerve compression. This method is particularly suitable for cervicogenic headaches and tension-type headaches.
Before treatment, the chiropractor will examine the cervical spine, assess range of motion, joint, muscle, and nerve status, and order imaging such as X-rays when necessary. This process helps identify the exact cause of the headache and develop a treatment plan tailored to each patient.
Based on the examination results, the chiropractor will perform manual adjustment techniques with precise force to restore natural movement of the cervical joints, reduce pressure on soft tissues and nerves. When the pain-causing mechanism improves, pain radiating from the neck to the back of the head, temples, or around the eyes will also decrease.
In addition to chiropractic adjustments, the treatment protocol at international musculoskeletal clinics like Chiro Lifestyle also incorporates advanced physiotherapy modalities. Typical examples include class IV laser supporting improved blood circulation and reducing inflammation in the neck area. Electrical stimulation therapy helps reduce pain signals transmitted to the nervous system, relax muscles, and relieve sensations of tightness in the neck and shoulder region.
After cervical spine function has improved, the rehabilitation therapist will guide the patient through personalized exercises to strengthen the deep neck muscles. This muscle group is essential for supporting the head, stabilizing the cervical spine, improving posture, and reducing the risk of recurrent headaches.
As a specialty clinic for Musculoskeletal and Spinal Neurology, Chiro Lifestyle pursues safe, comprehensive, and sustainable headache treatment protocols. The goal is not only pain relief, but also accurate identification of the cause, restoration of cervical spine function, and helping patients maintain a better quality of life.
