Tension Headache

Tension headache is the most common type of primary headache, characterized by mild to moderate pain that is often described as a constant pressure or tightness, like a band around the head. It typically affects both sides of the head (bilateral) and does not worsen with routine physical activity. Unlike migraines, tension headaches are generally not associated with severe symptoms such as nausea, vomiting, or significant sensitivity to light (photophobia) or sound (phonophobia), or if present, only one of these. They can be episodic (occurring less than 15 days per month) or chronic (occurring 15 or more days per month for at least three months).

The exact cause of tension headache is not fully understood, but it is believed to involve a combination of factors. Stress is a primary trigger, leading to muscle tension in the head, neck, and shoulders. Poor posture, prolonged fixed positions (e.g., computer work), lack of sleep, emotional factors like anxiety and depression, and jaw clenching can contribute. While not directly genetic, a familial predisposition to headaches in general may exist. Environmental factors and lifestyle choices play a significant role.

The pathophysiology of tension headache is thought to involve both peripheral and central mechanisms. Peripherally, increased tenderness of pericranial muscles (muscles of the scalp, neck, and shoulders) is a consistent finding, potentially due to sustained muscle contraction or ischemia. Centrally, chronic tension headaches may involve altered pain processing in the central nervous system, leading to central sensitization. This can result from prolonged nociceptive input from the pericranial muscles, leading to a lowered pain threshold and increased excitability of neurons in the pain pathways. Neurotransmitter imbalances, particularly involving serotonin and norepinephrine, are also implicated in pain modulation.

Tension headache is the most prevalent type of headache globally, affecting a vast majority of the population at some point in their lives. Episodic tension headaches have a lifetime prevalence of 30% to 78%, while chronic tension headaches affect 1% to 3% of adults. It can occur at any age but is most common in individuals aged 20 to 50 years. While episodic tension headaches show a slight female predominance, chronic tension headaches are more common in women.

• Stress (physical or emotional)
• Poor posture
• Lack of sleep or irregular sleep patterns
• Fatigue
• Skipped meals or dehydration
• Anxiety and depression
• Clenching jaw or teeth grinding (bruxism)
• Eye strain
• Caffeine withdrawal
• Head or neck injury history

A. Early Symptoms

• Mild pressure or tightness in the head


• Slight tenderness in scalp, neck, or shoulder muscles B. Common Symptoms


• Bilateral (affecting both sides) head pain


• Pressing or tightening (non-pulsating) quality


• Mild to moderate pain intensity


• Not aggravated by routine physical activity


• No nausea or vomiting


• Absence of severe photophobia (light sensitivity) or phonophobia (sound sensitivity), or only one of these C. Advanced Symptoms


• Increased frequency and duration of headaches (for chronic tension headache, daily or near-daily occurrence)


• Persistent muscle tenderness in the head, neck, and shoulders


• Increased impact on daily activities and quality of life D. Emergency Symptoms


• Sudden, severe headache (thunderclap headache)


• Headache with fever, stiff neck, rash


• Headache following head injury


• Headache with confusion, weakness, numbness, vision changes, or difficulty speaking


• Headache that is new or different in pattern, especially in individuals over 50

• Vital signs: Usually normal.
• Inspection: No obvious deformities or skin changes.
• Palpation: Tenderness upon palpation of pericranial muscles (temporalis, masseter, sternocleidomastoid, trapezius, splenius capitis). May find myofascial trigger points.
• Auscultation: No specific findings.
• Neurological Exam: Typically normal, with no focal neurological deficits.

A. Clinical Assessment
Diagnosis is primarily based on detailed patient history and physical examination, conforming to the International Classification of Headache Disorders (ICHD-3) criteria.
B. Laboratory Testing
Not typically indicated for the diagnosis of primary tension headache.
C. Imaging Studies
Generally not needed unless "red flag" symptoms are present, suggesting a secondary cause.
D. Functional Tests
None specific.
E. Biopsy Findings
Not applicable.
F. Genetic Testing
Not applicable.
G. Differential Diagnosis
Key for distinguishing from other primary headaches (migraine, cluster) and secondary headaches.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: To rule out systemic infection, inflammation, or anemia that might present with headache symptoms or contribute to overall malaise.
Expected Findings: Normal
Interpretation: No evidence of infection, inflammation, or anemia contributing to headache. Comprehensive Metabolic Panel (CMP)
Type: Blood Test
Purpose: To assess kidney function, liver function, and electrolyte balance, ruling out metabolic disturbances that could cause or exacerbate headache.
Expected Findings: Normal
Interpretation: No significant electrolyte imbalances or organ dysfunction contributing to headache.

Computed Tomography (CT) Scan of the Head
Purpose: To rapidly rule out acute intracranial pathologies such as hemorrhage, stroke, or large tumors if "red flag" symptoms are present.
Typical Findings: Normal in primary tension headache. May show other pathologies if a secondary cause is identified.
Clinical Importance: Used in emergency settings or when there is concern for acute, life-threatening conditions. Magnetic Resonance Imaging (MRI) of the Brain
Purpose: To provide a more detailed view of brain structures, detecting subtle lesions, inflammation, or other chronic conditions not visible on CT, especially if headaches are persistent, atypical, or accompanied by neurological deficits.
Typical Findings: Normal in primary tension headache.
Clinical Importance: Used when red flags persist despite normal CT, or for atypical headache patterns requiring comprehensive evaluation.

• Migraine: Often unilateral, throbbing, moderate to severe, with nausea/vomiting and/or photophobia/phonophobia, aggravated by activity.
• Cervicogenic Headache: Pain originating from the neck, often unilateral, restricted neck range of motion, head pain reproduced by neck movements.
• Medication Overuse Headache (MOH): Daily or near-daily headache due to chronic overuse of acute headache medications.
• Sinusitis: Headache accompanied by facial pain/pressure, nasal congestion, fever, and purulent discharge.
• Cluster Headache: Severe, unilateral, orbital/temporal pain, with associated autonomic symptoms (e.g., lacrimation, ptosis, nasal congestion) on the affected side.

• Medication Overuse Headache (MOH) due to frequent use of acute pain relievers.
• Depression and anxiety, often comorbid with chronic tension headache.
• Decreased quality of life, impaired work productivity, and social functioning.
• Sleep disturbances.

A. Lifestyle Modifications

• Stress management techniques (mindfulness, meditation, yoga)


• Regular exercise


• Adequate sleep hygiene


• Maintaining good posture and ergonomic work setup


• Regular meals and hydration


• Avoiding identified triggers B. Preventive Measures


• Biofeedback


• Cognitive Behavioral Therapy (CBT)


• Acupuncture


• Physical therapy for neck and shoulder muscle tension C. Medical Treatment

• None indicated for primary tension headache. E. Interventional Procedures


• Trigger point injections (local anesthetic, sometimes steroids) for specific areas of muscle tenderness. F. Rehabilitation


• Physical therapy, massage therapy, and chiropractic care to address musculoskeletal imbalances and muscle tension. G. Emergency Management


• No specific emergency management for uncomplicated tension headache. Emergency treatment focuses on ruling out and treating secondary causes if red flag symptoms are present.

The prognosis for episodic tension headache is generally good, with most individuals finding relief with over-the-counter medications and lifestyle adjustments. Chronic tension headache can be more challenging to manage, often requiring a multi-faceted approach involving preventive medications, lifestyle changes, and psychological therapies. While it can significantly impact quality of life, it is generally not life-threatening and can often be controlled.

• Primary Prevention: Regular stress management, maintaining good posture, regular exercise, adequate hydration, consistent sleep schedule, and avoiding known triggers.
• Secondary Prevention: Early and appropriate treatment of episodic headaches to prevent progression to chronic forms, and adherence to preventive medication regimens for chronic cases.
