HEADACHE AND FACIAL PAIN
Please read our disclaimer
About 21% of the adult population develops headache in
any 2-week period.
CAUSES OF HEADACHE (Hyperlinks provide more detail).
- Vascular (Migraine, Cluster,
arteritis, vascular malformations)
- Musculoskeletal (tension, cervical, Chiari
- Infectious (sinus, osteomyelitis, dental, encephalitis or meningitis)
MISCELLANEOUS MINOR CAUSES OF HEADACHES
- Dental including TMJ (usually stress related, common), micro-abscess.
- Sinus (about 10% of all HA)
- Iatrogenic headache (due to vasodilator medications such as NTG, isordil, procardia:
- Cervical (due to arthritis, common, easily diagnosed on exam)
- Hypertensive (25% increase in BP or > 180/130, bilateral, constant, moderately
- Ocular -provoked by near viewing or new glasses, glaucoma, rare (Gil Gouvea
R et al, 2002)
- Increased intracranial pressure (similar to hypertensive in symptoms/signs, very rare,
- Temporal arteritis (very rare). Unilateral, tender temporal artery, jaw claudication,
Polymyalgia. High sed rate. Trial of steroids if sed-rate is high.
- Aneurysmal (similar to migraine, rare - 28,000/year compared to 50 million
- Chiari Malformation - type I (CM-I). Headache is common (about 50%). Characteristic
headaches are brief, occipital or nuchal, triggered by cough, straining, postural
straining. Caused by transient tonsillar herniation. There are also
long-lasting headaches in CM-I of unclear etiology.
- Quality: throbbing, constant, shooting, shock, bizarre
- Location: hemicranial, front, back, top, sides
- Timing (may need a headache diary)
- Determine how long it takes for headache to reach maximum intensity
- Duration and periodicity
- Associations (foods like MSG or alcohol, menses, stress, sleep)
- Social history (especially, litigation)
- Past medical history (head-trauma, medications)
- Fever and weight loss suggest abnormality -- 80% of AIDs patients presenting
with new headache have incracranial mass
- Review of systems (such as previous cancer, etc).
- Family history (Migraine, Aneurysm)
- Previous studies
Examination is usually normal unless having a headache.
- Blood Pressure (important!)
- Vision and Fundi (anisometropia, papilloedema, hypertensive change)
- TMJ: crepitus/clicking, put fingers in ears and pull forward while jaw is opening.
- Myofascial pain: pain on lateral movement of jaw.
- Neck: Spurling's maneuver, check for spasm of neck muscles, try traction
- Temporal Arteries (tenderness, indurated, relieve headache)
- Carotid Compression (relieve or increase headache, avoid in vasculopaths)
- Neurological screening examination: Reflexes, Babinski, coordination
LABORATORY TESTS FOR HEADACHE
- ESR if temporal arteritis suspected
- Sinus X-rays, endoscopy or CT if sinusitis suspected
- MRI - if central signs, or increase intensity, or from Mexico (cystacercosis
- Cervical Spine - cervical headache
- LP - if meningitis suspected
- MRA if vascular lesion suspected
Guidelines for scans. MRI single most useful test. CT acceptable if index of suspicion
is low. PET no indication.
