Tension-Type Headache
A clinically focused guide to recognising tension-type headache, excluding dangerous secondary causes, using conservative and limited analgesic care, and applying Indian supervision and access safeguards.
Summary
Tension-type headache (TTH) is a primary headache diagnosis made from a characteristic pattern after proportionate assessment for a secondary cause. It is usually bilateral, pressing or tightening, mild or moderate, and not made worse by ordinary activity. Nausea, vomiting, and prominent migrainous sensory symptoms argue for another diagnosis, although real patients may have overlapping headache phenotypes. ‘Stress headache’ is an unhelpful label: stress, sleep disruption and musculoskeletal discomfort can coexist, but do not establish cause.
The immediate question is safety. Abrupt maximal-onset pain, fever with deterioration, focal neurology, reduced consciousness, papilloedema symptoms, painful red eye, head injury, pregnancy-related concern, immunosuppression or a material change from the usual pattern requires a secondary-headache pathway. A normal routine examination in a stable person with a familiar phenotype supports a positive clinical diagnosis; imaging merely for reassurance is not routinely recommended.
Management starts with explanation, a diary, sleep and activity review, and selective simple analgesia. Repeated analgesic use can itself perpetuate headache. This educational draft does not diagnose an individual, replace urgent assessment, or override an Indian clinician’s examination, local formulary, pregnancy precautions or referral protocol.
How Common Is It?
TTH is described by WHO as the most common primary headache disorder, but an apparently simple prevalence figure conceals differences in recall period, diagnostic criteria, age, sex, care setting and whether infrequent attacks are counted. WHO notes that headache disorders are common and under-recognised globally; this supports a public-health perspective, not a precise Indian prevalence estimate. Population estimates from other countries should not be presented as the burden in India without an Indian sampling frame and the same case definition.
Episodic TTH is classified by attack frequency, while chronic TTH involves headache on 15 or more days per month for more than three months. Frequency matters because it changes disability, the risk of medication overuse and the value of a diary, but frequency alone does not prove that every painful day has the same mechanism. A person may have TTH on some days and migraine, cervicogenic pain or medication-overuse headache on others.
Primary-care workload also depends on anxiety about serious disease, absence from study or work, sleep and mental-health symptoms, and access to affordable assessment. Local services should measure their own patterns rather than import an unsupported national rate. The evidence sources here are international classification and guidance; they do not establish Indian incidence, referral capacity or medicine availability.
Risk Factors
TTH has no single confirmatory exposure and the word ‘risk factor’ should not imply that the patient caused the headache. Clinical histories often identify irregular sleep, prolonged visual or desk work, missed meals, dehydration, psychological distress, jaw clenching, neck discomfort, low physical activity or a recent increase in workload. These are potentially modifiable associations or triggers to explore, not diagnostic tests. Asking what changed before onset is more useful than assigning blame.
Frequent pain days and frequent use of paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), combination analgesics, caffeine-containing products or opioids raise concern for medication-overuse headache. A precise count of days on which each acute medicine is taken, including non-prescription and traditional products, is safer than asking only for ‘tablets’. Migraine features, depressed mood, anxiety, poor sleep and chronic musculoskeletal pain may coexist and need their own assessment.
New headache after 50 years, cancer, HIV or other immunocompromise, anticoagulation, pregnancy or postpartum change, systemic illness, recent trauma, exertional or Valsalva trigger, or a rapidly altered phenotype is not a TTH risk profile; it is a reason to revisit secondary causes. In India, long travel, self-medication, over-the-counter combination analgesics and variable access to eye, dental, mental-health and neurology care can alter the pathway, but this guide makes no quantified Indian access claim.
Diagnosis
History
Ask onset, time to peak, duration, days per month, pain quality, site, intensity, activity effect, associated nausea, vomiting, photophobia, phonophobia, aura, autonomic symptoms, fever, weight loss, trauma, medicines, pregnancy possibility and family history. ICHD-3 typical infrequent or frequent episodic TTH lasts 30 minutes to seven days, has at least two of bilateral location, pressing or tightening quality, mild or moderate intensity, and no aggravation by routine activity; it has neither nausea nor vomiting and no more than one of photophobia or phonophobia. Record all analgesic days and functional impact in a diary.
Examination
Measure vital signs and perform a focused general and neurological examination, including conscious state, cranial nerves, limbs, gait when appropriate and fundus assessment where competent and indicated. Inspect the eye when pain, visual symptoms or red eye suggest acute glaucoma. Examine neck and jaw only as part of a broader assessment; pericranial tenderness may occur but does not independently diagnose TTH. Abnormal neurology, meningism, systemic illness, trauma signs or raised-pressure features changes the question from headache classification to urgent cause finding.
Investigations
TTH has no diagnostic blood test or scan. In a stable person with a typical recurrent primary-headache pattern and normal examination, select tests only to answer a clinical question. Current guidelines advises against neuroimaging solely for reassurance after diagnosis. Urgent CT, MRI, lumbar puncture, inflammatory markers, pregnancy testing, eye pressure assessment or other investigations depend on the red-flag hypothesis, timing and local service pathway. Document why a test is needed and act on abnormal findings; a normal scan does not make an atypical phenotype automatically TTH.
Differential Diagnosis
Migraine is the most important competing primary diagnosis. Compared with TTH, migraine is more likely to be pulsating, moderate or severe, aggravated by routine activity, and associated with nausea, vomiting, photophobia or phonophobia; chronic migraine and chronic TTH may overlap, and international guidelines recommends diagnosing chronic migraine if migrainous features are present. Cluster headache is usually strictly unilateral, severe, shorter and accompanied by ipsilateral cranial autonomic signs or restlessness.
Medication-overuse headache should be considered when a pre-existing headache becomes frequent in association with regular acute medicines. Cervicogenic headache, temporomandibular disorders, refractive or ocular disease, sinus disease and dental pain can contribute to head or face pain, but location near the neck, eyes or sinuses alone does not establish the cause. Depression, anxiety and sleep disorder may amplify symptoms but should not be used to dismiss a new or changing headache.
Secondary causes include subarachnoid haemorrhage, meningitis or encephalitis, cerebral venous thrombosis, intracranial mass or pressure disorder, giant-cell arteritis, acute angle-closure glaucoma, hypertensive emergency, carbon-monoxide exposure and trauma-related bleeding. Their probability comes from onset, trajectory, systemic and neurological features, examination and context. Use an emergency pathway for a dangerous possibility; do not make a reassuring TTH diagnosis before the history has addressed it.
Management
Give a positive explanation of the phenotype and agree goals such as fewer disabling days, less self-medication and return to ordinary activity. A headache diary for at least eight weeks can record frequency, duration, severity, symptoms, menstrual relation where relevant, possible triggers and every acute medicine. It supports diagnosis, identifies medication overuse and tests whether a chosen change is useful. Encourage regular sleep, hydration and meals, paced breaks from sustained posture or screen work, graded physical activity and management of relevant anxiety, depression, jaw clenching or neck symptoms; these measures are individualised supports, not proof that the pain is psychological.
For acute TTH, current guidelines advises considering aspirin, paracetamol or an NSAID after preference, comorbidity and adverse-effect risk are assessed, and advises against opioids. Use the lowest effective exposure for the shortest necessary period, and review frequent use rather than escalating. For chronic TTH, current guidelines allows consideration of a course of up to ten acupuncture sessions over five to eight weeks. Evidence and access vary; this is not a mandate to purchase treatment or a substitute for reassessing diagnosis.
Arrange review if the pattern changes, functioning worsens, acute medicines become frequent, or initial conservative care fails. Treat coexisting migraine or medication overuse on its own evidence-based pathway. Imaging may be appropriate for a new clinical concern, but not as a routine response to persistent anxiety with an otherwise typical established diagnosis. Safety-net advice must name the symptoms that require urgent assessment.
Prescribing Information
Paracetamol, aspirin and NSAIDs are not interchangeable ‘headache tablets’. Before prescribing or recommending one, confirm age, allergy, current products, total daily exposure, pregnancy or conception possibility, peptic-ulcer or gastrointestinal-bleeding history, renal disease, liver disease, cardiovascular risk, anticoagulants, antiplatelets and interacting medicines. Aspirin-containing preparations should not be offered to people under 16 years because of Reye syndrome risk. The appropriate product, dose, interval, maximum dose and duration must come from the current Indian formulary, labelled preparation and supervising prescriber; this guide deliberately does not supply a universal dose.
Avoid opioids for acute TTH. They add sedation, constipation, dependence and medication-overuse risk without being recommended by current guidelines for this indication. Combination analgesics and repeated self-medication deserve active reconciliation because patients may not recognise caffeine, an NSAID or paracetamol in multiple brands. Do not layer products containing the same ingredient. Escalating analgesia when headache frequency rises can mask medication overuse and delay reconsideration of the diagnosis.
If another treatment is considered for chronic symptoms, clarify the target diagnosis, evidence, contraindications, pregnancy considerations, monitoring and stop rule. Acupuncture guidance is based on an international pathway and availability, provider regulation and affordability differ in India. Pharmacotherapy for a comorbid mood, sleep, jaw or migraine disorder should be chosen for that diagnosed condition, not presented as routine TTH prescribing. Seek pharmacist or specialist input for uncertainty, polypharmacy, renal or hepatic impairment and recurrent analgesic use.
When to Refer
Refer urgently or send to emergency care for a thunderclap onset, fever with worsening headache, new focal neurological deficit, seizure, confusion or reduced consciousness, papilloedema symptoms, acute painful red eye or visual loss, suspected meningitis, trauma with deterioration, pregnancy-associated concern, or suspected raised intracranial pressure. A patient with an abnormal examination needs cause-directed assessment rather than a routine headache clinic appointment. If acute danger is possible, stabilise, record times and observations, and transfer according to the local emergency system.
Neurology, general medicine or a dedicated headache service is appropriate for recurrent disabling headache with diagnostic uncertainty, chronic daily headache, suspected medication overuse that cannot be safely managed in primary care, atypical aura, treatment failure after a structured trial, or concern for a secondary disorder despite initial evaluation. Ophthalmology is urgent for painful red eye, visual loss or suspected acute glaucoma; dental, physiotherapy, mental-health or sleep services may be helpful only for an identified contributory problem.
The referral should state baseline and current pattern, onset, red flags assessed, examination, headache diary summary, all acute medicines and days used, pregnancy status where relevant, investigations and their rationale, treatments tried, response and functional impact. In low-resource settings, referral decisions must account for transport and access while preserving emergency thresholds. This guide cannot determine the nearest capable Indian facility or substitute for local triage rules.
Red Flags
A headache that reaches maximum intensity within five minutes is an emergency until subarachnoid haemorrhage and other vascular causes are assessed. Fever with worsening pain, neck stiffness, rash, altered behaviour or impaired consciousness raises infection or inflammation. New weakness, speech disturbance, visual loss, diplopia, seizure, gait change, confusion or persistent vomiting requires urgent neurological evaluation. Symptoms of acute angle-closure glaucoma include a painful red eye with visual disturbance and require urgent eye assessment.
current guidelines also identifies recent head trauma, exertional, cough, sneeze or Valsalva precipitation, orthostatic headache, symptoms suggesting giant-cell arteritis, a substantial change in characteristics, compromised immunity, brain-metastasising cancer and unexplained vomiting as reasons to consider investigation or referral. These features do not each prove a serious cause; they change the threshold for examination, investigation and escalation. New headache during pregnancy or postpartum, with hypertension or neurological symptoms, likewise needs an obstetric or emergency pathway rather than diagnostic reassurance.
Safety-net advice should be specific: seek urgent help for sudden severe onset, new weakness or speech/vision change, fainting, confusion, seizure, fever and stiff neck, head injury, rapidly progressive pain, persistent vomiting, or a new painful red eye. Worsening after an initial TTH diagnosis is not automatically treatment failure. Reassess the phenotype, medicines and examination. Do not advise a patient to wait for a routine appointment when red flags are present.
Indian Clinical Context
This draft is jurisdictionally framed for India but draws on WHO, ICHD-3 and international guidelines sources, not an Indian national TTH treatment standard. Their classification and safety principles can inform teaching; hospital referral pathways, medicine schedules, dispensing rules, pregnancy protocols and availability must be checked locally. Generic use of an international guideline should never be represented as an Indian legal, regulatory or government recommendation.
Practical assessment should ask about self-purchased analgesics, combination cold or pain remedies, use of traditional or unlabelled preparations, travel time to emergency care, vision and dental symptoms, sleep, work or study demands, and the language needed for a diary and safety-net instructions. These questions address access and communication without assuming that a patient’s income, culture or geography explains the headache. A paper diary may be more feasible than an app; a photograph of packages can clarify ingredient duplication when literacy or brand uncertainty limits history.
Primary-care settings without routine imaging can still make a careful clinical assessment, but cannot use resource limits to ignore red flags. Conversely, a normal scan obtained elsewhere does not replace a current history and examination. Refer or transfer when the required neurological, eye, obstetric or emergency assessment is unavailable. Indian epidemiology, local medicine availability and service capacity are uncertain in this source set and must be verified at institutional level before protocol design.
NMC Competency Mapping
The NMC Competency Based Medical Education Curriculum 2024 supports a supervised, integrated approach to a patient with headache rather than a claim that this guide maps to one invented code. Learners apply history taking, neurological examination, communication, pharmacology, pathology and emergency recognition to distinguish a likely primary headache from a potentially dangerous secondary syndrome. The official curriculum is the authority for local competency codes, phase placement and assessment; institutions should use their adopted competency ledger rather than infer a code from this text.
At knowledge level, a learner should compare TTH, migraine, cluster headache and medication-overuse headache and list vascular, infective, ocular, inflammatory, toxic and pressure-related red flags. At skills level, under appropriate supervision, the learner should take a structured headache and medication history, record vital signs, perform a focused neurological assessment, identify a painful red eye or neurological deficit, use a diary, and communicate why normal imaging is not a guarantee. They should explain the contraindication check before analgesia.
Students should not independently decide that a red flag is harmless, prescribe high-risk analgesics, perform lumbar puncture, diagnose papilloedema beyond competence, or delay transfer. Assessment can use a case with typical bilateral pressing pain and a second with thunderclap onset or visual symptoms, rewarding explicit escalation. This curriculum mapping is educational only and does not certify clinical competence, publication approval or authority to practise unsupervised.
Key Exam Pearls for NEET PG
TTH is classically bilateral, pressing or tightening, mild or moderate and not aggravated by routine activity. Typical attacks last 30 minutes to seven days. The ICHD-3 pattern requires at least two characteristic pain features, no nausea or vomiting, and no more than one of photophobia or phonophobia. Do not turn the word ‘tension’ into a diagnostic requirement for stress or tender muscles. A patient can have neck discomfort without proving cervicogenic headache.
The high-yield contrast is migraine: pulsating pain, greater intensity, aggravation by activity, nausea or vomiting, and sensory sensitivity make migraine more likely. In chronic headache, migrainous features should not be ignored; Current guidelines notes chronic migraine and chronic TTH overlap and directs diagnosis of chronic migraine if migraine features are present. Medication-overuse headache is a frequent trap: count medicine-use days, including non-prescription combination products.
For a typical stable diagnosis, do not choose imaging merely for reassurance. In a stem with sudden peak pain, fever, focal neurology, altered consciousness, eye pain with redness, exertional/Valsalva trigger, trauma or a major new pattern, the correct next step is evaluation for a secondary cause, not a stronger analgesic. For treatment, current guidelines supports paracetamol, aspirin or an NSAID after safety assessment and advises against opioids. Under-16 aspirin is unsafe because of Reye syndrome risk. Exam answers must still defer doses and individual contraindications to the current local formulary.
Frequently Asked Questions
Can tension-type headache be diagnosed without a brain scan in every patient?
No. A typical recurrent phenotype with a normal assessment often needs no scan solely for reassurance, but diagnosis depends on history and examination. Sudden onset, neurological deficit, fever, altered consciousness, painful red eye, trauma, pregnancy concern or a major change in pattern changes the question and may require urgent investigation or referral.
How does a headache diary make the diagnosis and treatment safer?
A diary records days affected, duration, severity, associated symptoms, triggers, menstrual relation where relevant and every acute medicine. Over at least eight weeks it can separate an infrequent pattern from chronic headache, expose medication overuse, reveal migraine features, measure treatment effect and provide a clearer referral summary than memory alone.
Why should opioids not be used for an uncomplicated tension-type headache attack?
Current guidelines advises against opioids for acute TTH. They can cause sedation, constipation, dependence and medication-overuse headache, while obscuring a changing clinical pattern. Repeated need for stronger analgesia should prompt diagnostic reassessment, medicine reconciliation and a discussion of non-drug measures or appropriate referral instead of automatic escalation.
Are stress reduction and posture changes enough treatment for chronic headache?
They can be useful individual supports, particularly when a diary identifies sleep disruption, sustained posture, jaw clenching or distress, but they neither prove cause nor replace assessment. Chronic, disabling or changing headache needs review for migraine, medication overuse and secondary causes. Treatment choices must account for the person’s comorbidities, access and safety risks.
