BASICS
Description
- Bilateral mild to moderate, nonthrobbing head pain or pressure
- Formerly known as muscle contraction headache, stress headache, idiopathic headache
- Types:
- Episodic TTH: ≥10 episodes lasting 30 min to 7 days
- Chronic TTH: ≥15 days/month for >3 months
Epidemiology
- Most common primary headache worldwide; second-most prevalent disorder overall
- Peak prevalence in 4th decade
- Episodic TTH decreases with age; chronic TTH increases
Etiology and Pathophysiology
- Multifactorial; peripheral nociceptor activation causes myofascial pain in episodic TTH
- Central sensitization leads to chronic TTH
- Nitric oxide implicated
Risk Factors
- Stress (mental/physical)
- Sleep changes
- Skipping meals, dehydration
- Dietary triggers (caffeine, alcohol, chocolate)
- Environmental factors (sun glare, odors, noise)
- Female hormonal changes
- Medications (nitrates, SSRIs, antihypertensives)
- Overuse of abortive medications
General Prevention
- Avoid triggers
- Exercise regularly
- Maintain sleep hygiene
- Limit caffeine and alcohol
- Stay hydrated
Commonly Associated Conditions
- Frequently coexists with migraine (83%)
- Anxiety and depression common comorbidities
DIAGNOSIS
History
- Thorough pain history: onset, location, quality, severity, associated symptoms, medications, trauma
- Pain described as dull, band-like, or pressure
- Diagnostic criteria (ICHD-3):
- Episodic TTH: ≥10 episodes lasting 30 min–7 days
- Chronic TTH: ≥15 days/month for >3 months, lasting hours to days or unremitting
- Rule out red flags for secondary headache
Physical Exam
- Usually normal
- Palpate pericranial muscles for tenderness
- Neurologic exam to exclude other causes
Differential Diagnosis
- Migraine, cluster headache
- Cerebrovascular disease, temporal arteritis
- Intracranial neoplasm, infection
- Medication overuse, caffeine dependency
- Temporomandibular joint syndrome, cervical spondylosis
Diagnostic Tests
- Labs and imaging not routinely required
- Consider MRI/CT if red flags or atypical presentation
- Headache diary helpful for tracking
TREATMENT
General Measures
- Relaxation techniques, rest in quiet/dark room
- Hot baths, neck and temple massage
Medications
First-Line
- NSAIDs (ibuprofen, naproxen), aspirin, acetaminophen for episodic TTH
Prophylaxis
- Amitriptyline first-line for chronic TTH (10 mg up to 100 mg QHS)
- Consider if depression, anxiety, insomnia present
Second-Line
- Caffeine combinations for episodic TTH
- Ketorolac IM for severe attacks
- Avoid opioids, butalbital-containing meds
Additional Therapies
- Stress management + amitriptyline best for chronic TTH
- Topiramate (limited evidence)
- Alternative TCAs (nortriptyline, protriptyline)
- Trigger point lidocaine injections; Botox evidence conflicting
Complementary & Alternative Medicine
- Topical tiger balm, peppermint oil
- Cognitive-behavioral therapy
- EMG biofeedback, relaxation
- Physical therapy, exercise
- Acupuncture (some evidence)
ONGOING CARE
Diet
- Identify and avoid dietary triggers
- Maintain regular meals
Patient Education
- National Headache Foundation and family doctor websites as resources
Prognosis
- Most cases intermittent and improve with age
Complications
- Medication-overuse headache
- NSAID-induced GI bleeding
- Dependence on narcotics
Clinical Pearls
- Typical tension headache is bilateral, mild/moderate, nonthrobbing without other symptoms
- NSAIDs are first-line abortive therapy; TCAs useful for prophylaxis though not FDA-approved
- Consider further evaluation if atypical features or treatment failure
- Avoid opioids or butalbital for recurrent headaches due to risk of MOH
