HEADACHE AND FACIAL PAIN

Timothy C. Hain, MD• Page last modified: August 20, 2020

About 21% of the adult population develops headache in any 2-week period.

CAUSES OF HEADACHE (links provide more detail).

1. Vascular (Migraine, Cluster,   arteritis, vascular malformations)
2. Musculoskeletal
   1. tension,
   2. cervical
   3. Chiari malformation
   4. TMJ
3. Sinus (about 10% of all HA, very often misdiagnosed)
4. Post-trauma
5. Altitude induced headaches
6. Infectious (osteomyelitis, dental, encephalitis or meningitis)
7. Neoplastic (i.e. brain tumor)
8. Psychogenic

See here for a separate discussion of ear pain.

 

MISCELLANEOUS MINOR CAUSES OF HEADACHES

• Dental including TMJ (usually stress related, common), micro-abscess.
• Iatrogenic headache (due to vasodilator medications such as NTG, isordil, procardia: common).
• Hypertensive (25% increase in BP or > 180/130, bilateral, constant, moderately common)
• Ocular -provoked by near viewing or new glasses, glaucoma, rare (Gil Gouvea R et al, 2002)
• Increased intracranial pressure and hydrocephlaus (similar to hypertensive in symptoms/signs, very rare, worsening course)
• Decreased intracranial pressure
• 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 migraines/year)
• 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.

Headaches can also be sorted by their timing:

• Chronic daily headache
  • Chronic migraine
  • chronic tension headache
  • hemicrania continue
  • medication overuse headache
• Thunderclap headache
  • Subarachnoid hemorrhage
  • Sentinal headache of aneurysm
  • hypertensive crisis
  • pituitary apoplexy
  • spontaneous CSF leak
  • thrombosis or expansion of unruptured aneurysm
  • "primary" thunderclap headache
  • exertional headache
  • cough headache
  • sexual headache

 

HEADACHE: HISTORY

• 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

HEADACHE: EXAMINATION

Examination is usually normal unless having a headache.

• Blood Pressure (important!)
• Vision and Fundi (anisometropia, papilloedema, hypertensive change)
• Ears/Sinuses
• 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 risk)
• Cervical Spine - cervical headache
• LP - if meningitis suspected
• MRA if vascular lesion suspected

Tests usually not helpful

• EEG

Guidelines for scans.

• MRI single most useful test.
• CT acceptable if index of suspicion is low.
• PET no indication.
