HEADACHE (MIGRAINE, TENSION HEADACHES)

Chronic headaches can come from many different factors, broadly classified into primary and secondary causes:

Primary headaches occur when the headache itself is the underlying disorder rather than a symptom of another condition.

• Tension and Stress: Physical or emotional stress can contribute to muscle tension in the head, neck, and shoulders, which may trigger tension-type headaches. In fast-paced environments, prolonged stress and long working hours may increase the likelihood of stress-related headaches.
• Brain Signalling and Neurochemical Changes: Changes in brain signalling, neurotransmitters such as serotonin, and altered pain processing pathways are believed to play a role in migraines and other primary headache disorders.
• Genetic Predisposition: Family history of migraines or cluster headaches increases the likelihood of developing these conditions, suggesting a genetic susceptibility.
• Sleep Patterns: Irregular sleep schedules, insufficient sleep, oversleeping, or poor sleep quality can trigger headaches in some individuals.
• Dietary Triggers: Certain foods, alcohol, caffeine, or skipping meals may trigger headaches in susceptible individuals.
• Environmental Factors: Bright lights, loud noises, strong smells, and weather changes are known triggers for some people, particularly those with migraines.

Unlike primary headaches, secondary headaches occur when an underlying medical condition triggers the headache pain. Identifying these causes is important when evaluating chronic headaches, persistent headaches, or headaches that suddenly change in pattern or severity.

Secondary headaches can arise from common and treatable conditions, but in some cases they may indicate a more serious health issue that requires medical attention. Common causes include: 

• Sinus Infections and Upper Respiratory Illness: Inflammation or infection in the sinuses can cause pressure and pain around the forehead, cheeks, or behind the eyes. These headaches often worsen when bending forward.
• Medication Overuse Headache: Frequent use of pain medications for migraines or other headaches can paradoxically lead to rebound headaches, resulting in persistent or chronic headache symptoms.
• Neck and Spine Problems: Conditions affecting the cervical spine, muscle strain, poor posture, or nerve irritation in the neck can lead to cervicogenic headaches, where pain radiates from the neck to the back or sides of the head.
• Hormonal Changes: Hormonal fluctuations during menstruation, pregnancy, or menopause can trigger headaches in some individuals.
• Systemic Infections: Viral or bacterial infections such as flu, sinusitis, or meningitis may cause headaches as part of the body’s inflammatory response.
• High Blood Pressure and Vascular Conditions: Severe hypertension or disorders affecting the blood vessels in the brain can sometimes present with headache symptoms.

In rare cases, chronic or severe headaches may be linked to more serious conditions, including:

• Stroke
• Brain tumours
• Bleeding in the brain (such as a ruptured aneurysm)
• Giant cell arteritis
• Because secondary headaches can sometimes signal an underlying health problem, new, worsening, or persistent headaches should be evaluated by a doctor, particularly if they occur with symptoms such as fever, confusion, vision changes, weakness, or neck stiffness.

Headaches can occur in several different forms. Each type has its own pattern of symptoms and triggers. Common headache types include:

Chronic headache symptoms can range from general discomfort to severe, daily limitations. If your headaches are severe or accompanied by concerning symptoms, it’s best to have them assessed by a headache specialist. Common symptoms of headache include:

• Throbbing or Pulsating Pain: Often seen in migraines, this pain may feel like a rhythmic pounding in your head. Physical movement can make the discomfort worse.
• Tight, Pressure-Like Sensation: Typical of tension headaches, many people describe this as a tight band or pressure around the head. 
• Pain on One or Both Sides of the Head: The location can vary depending on the headache type. Migraines often affect one side, while tension headaches usually involve both sides. 
• Nausea or Vomiting: Some headaches, especially migraines, may come with nausea and occasionally vomiting. 
• Dizziness or Visual Changes: You may notice flashing lights, zigzag patterns, or blind spots before or during a migraine attack. This is known as an aura. 
• Sensitivity to Light, Sound, or Smells: During severe headaches, bright lights, loud sounds, or strong smells can make the pain feel worse, leading many people to seek a dark, quiet place to rest. 
• Severe Pain Around One Eye: Cluster headaches often cause intense pain around or behind one eye. This may also be accompanied by tearing, redness of the eye, or nasal congestion on the same side. 

Seek immediate emergency care if you experience:

• Sudden, severe headache unlike any you’ve had before (“thunderclap headache”) 
• Headache accompanied by fever, stiff neck, confusion, vision changes, difficulty speaking, numbness, or weakness 
• Headache after head injury or trauma 
• Headache that worsens over days and changes in character 
• Progressive headache with neurological symptoms suggesting stroke 

These may indicate life-threatening conditions requiring immediate intervention. 

If your chronic headaches are mild or moderate, you may benefit from conservative treatments, including:

Our doctor may begin with commonly used pain relievers to help manage stress-related headaches. For some patients, stronger non-steroidal anti-inflammatory medications (NSAIDs) may be prescribed to better control inflammation and reduce pain. Because stress headaches are often linked to tight or overworked muscles, muscle relaxants may also be used. These medications help ease muscle spasms, allowing the head and neck to relax and bringing relief from the tension that triggers the headache.

For frequent headaches, several medication classes can reduce frequency and severity:

• Beta-Blockers: These medications help calm overactive nerve signals involved in migraine attacks and may reduce how often migraines occur. They are commonly used for blood pressure control as well, but may not be suitable for patients with asthma. 
• Anti-Serotonergic Medications: Serotonin plays a role in migraine development. These medications help regulate serotonin activity in the brain, reducing the likelihood of migraine attacks. 
• Tricyclic Antidepressants: These medicines can help stabilise nerve signalling involved in chronic headaches. They are often particularly helpful for patients whose migraines are linked to poor sleep or difficulty falling asleep. 
• Antiepileptic Medications: Originally developed to treat seizures, these medications can also help reduce nerve activity that transmits pain signals, lowering the frequency of migraine episodes. 
• Calcium Channel Blockers: These medications regulate calcium movement within nerve cells, helping to reduce excessive nerve activity that can trigger headaches. 
• Angiotensin II Blockers: Commonly used for blood pressure control, these medications may also help reduce the frequency of migraine attacks in some patients. 

If your symptoms do not improve, minimally invasive treatments can target the real source of pain without the need for open surgery. At Singapore Paincare, we offer precise procedures designed to relieve pain at its origin.

Targeted injections delivered directly to specific muscle groups can decrease the frequency and severity of chronic migraines and tension headaches. These precisely targeted treatments provide long-term relief with minimal recovery time.

 A same-day outpatient procedure using radiofrequency heat energy to deactivate painful nerve branches in your neck that cause headaches. Performed under light sedation, this minimally invasive treatment effectively desensitizes nerves carrying pain signals, providing sustained relief.

Surgery is generally reserved for cases where non-surgical methods have not provided sufficient relief and specific underlying causes are identified. 

May be recommended if you experience no improvement despite medications. The procedure involves implanting a device with electrodes and pulse generator to reduce migraine pain signals. Current evidence suggests varying effectiveness, with success reported in approximately 60% of patients. Since surgery carries associated risks, complications, and recovery time, the decision should be carefully weighed.

While not all headaches are preventable, these lifestyle and management strategies can reduce frequency and severity:

• Stress Management: Given Singapore's fast-paced lifestyle, managing stress effectively through mindfulness, relaxation exercises, or meditation can reduce tension headache triggers 
• Consistent Sleep Schedule: Maintain regular sleep patterns—going to bed and waking at consistent times—to stabilize brain chemistry 
• Dietary Awareness: Identify and avoid food triggers common for migraines (aged cheeses, processed meats, chocolate, alcohol) 
• Avoid Medication Overuse: Paradoxically, frequent use of headache medications can cause rebound headaches. Use medications as directed and consult specialists for proper pain management 
• Ergonomic Adjustments: For office workers, ensure correct posture, proper desk setup, and regular breaks to prevent neck and shoulder tension contributing to headaches 
• Regular Exercise: Physical activity helps reduce stress and improve overall well-being, potentially reducing headache frequency 
• Stay Hydrated: Dehydration is a common headache trigger, particularly important in Singapore's tropical climate
