Headache
Overview
Red flags
History and physical
New headache at age ≥ 50 years
Sudden onset, worse with position change, fever, malaise, myalgia, vision changes
Focal/lateralizing neurologic deficit on exam
Specific considerations
Intracranial hemorrhage (obtain STAT CT): Sudden onset, worse with position changes (e.g. supine vs. upright), new onset neurologic deficits
Intracranial mass (obtain MRI with contrast): Age ≥ 50 years with new onset neurologic deficit
Systemic symptoms, e.g. fever, malaise, myalgias: Consider infectious etiology (see below)
Elderly patient with fever, monocular visual loss, jaw claudication: Consider temporal arteritis
Treatment options
Non-pharmacologic
Home: Relaxation techniques and cervical exercises
Office: CBT, osteopathic manipulation, acupuncture
Pharmacologic options pending headache type
Consider neurology referral for refractory symptoms
Bilateral
Common
Tension headache
Bilateral band-like pressure that builds in intensity
Treatment options
Naproxen 550 mg BID
Acetaminophen 250 mg/aspirin 250 mg/caffeine 65 mg x 2 tablets
Reduction in frequency: Gabapentin 300 mg QHS; titrate to 300 mg TID as needed
Reduction in severity and duration: Amitriptyline 25 mg, tizanidine 2 mg TID (MDD 36 mg/day)
Medication withdrawal headache: Review caffeine, alcohol, and analgesic use; taper offending agent
Menstrual headache
Infectious
Uncommon
Emergent
Subarachnoid hemorrhage
Hypertensive encephalopathy
Benign intracranial hypertension
Carbon monoxide poisoning
Unilateral
Pounding quality, duration 4-72 hours, unilateral, associated with nausea, and disabling
Avoid schedule changes, food/beverage triggers (e.g. caffeine and alcohol), environmental triggers
Abortive therapy with ibuprofen, sumatriptan
Four or more H/A per month: Prophylactic therapy with depakote, topiramate, propranolol, or amitriptyline
Cluster headache
Symptoms lasting 15 minutes to 3 hours
Unilateral orbital, supraorbital, or temporal pain
Autonomic phenomenon, e.g. ptosis, miosis, lacrimation, conjunctival injection, rhinorrhea
Consider CT vs. MRI to r/o intracranial mass or other abnormalities
Acute treatment: One spray 20 mg intranasal sumatriptan in nostril on affected side (MDD 40 mg/24 hours)
Temporal (giant cell) arteritis
Associated with fever, monocular visual loss, jaw claudication
ESR 40 to 100
Refer for temporal artery biopsy and start prednisone 1 mg/kg (MDD 60 mg/day)
Intracranial mass
