How should a frontal headache persisting two weeks after a fall be managed in the absence of other symptoms?

Management of Persistent Frontal Headache Two Weeks After Fall

For a frontal headache persisting two weeks after a fall with no other symptoms, provide systematic information and reassurance, initiate graded physical exercise, and consider phenotype-guided pharmacological treatment if symptoms are significantly impacting function.

Initial Assessment and Red Flags

At two weeks post-injury, you are now dealing with subacute postconcussive symptoms. First, verify there are truly no other concerning features:

• No loss of consciousness at time of injury
• No amnesia for the event
• No neurological deficits (vision changes, weakness, numbness)
• No worsening headache pattern
• No anticoagulant or antiplatelet medication use
• No repeated vomiting or altered mental status

If any of these are present, neuroimaging with CT is warranted. However, if the patient is neurologically intact with isolated headache, imaging is typically not required at this stage 1.

Primary Treatment Approach

1. Systematic Information and Advice (First-Line)

Provide structured education about expected recovery:

• Most postconcussive headaches resolve within 4 weeks
• Symptoms do not indicate structural brain damage
• Early return to normal activities promotes recovery
• Avoiding activity can paradoxically prolong symptoms

This intervention reduces overall symptom burden and prevents chronicity 2.

2. Graded Physical Exercise (Strongly Recommended)

Initiate light aerobic exercise immediately - this is one of the most evidence-based interventions:

• Start with 15-20 minutes of light aerobic activity (walking, stationary bike)
• Gradually increase intensity over 1-2 weeks
• Exercise should be sub-symptom threshold (not exacerbating headache significantly)
• Minimum 1 time per week for 4 weeks, though daily is preferable

This approach improves overall symptom burden, physical functioning, emotional symptoms, and quality of life 2. Early aggressive treatment prevents chronicity 3, 4.

Pharmacological Management Based on Headache Phenotype

Since you're describing a frontal headache, characterize the pain pattern:

If Tension-Type Features (Bilateral, Pressing, Non-Pulsating):

• First-line: NSAIDs for acute episodes (avoid daily use to prevent medication overuse)
• Prophylaxis if frequent: Amitriptyline 10-25mg at bedtime (also addresses sleep disturbance, a common comorbidity)

If Migraine-Like Features (Unilateral, Throbbing, Photophobia, Nausea):

• Acute treatment: Triptans or NSAIDs
• Prophylaxis: Consider topiramate, propranolol, or anti-CGRP therapies 5

Mixed Features (Most Common):

• Treat the predominant phenotype
• Consider prophylaxis if headaches occur >2 days per week 6

Critical caveat: Avoid daily analgesic use. Medication overuse headache develops easily in post-traumatic headache and significantly complicates management 3, 4.

Additional Considerations

Cervicogenic Component

Given the frontal location and fall mechanism, assess for neck involvement:

• Palpate cervical paraspinal muscles and occipital region
• Check cervical range of motion
• If restricted or tender, consider manual therapy/physiotherapy 2

Risk Factors for Prolonged Recovery

This patient may be at higher risk if:

• Female sex
• History of prior concussion
• Pre-existing anxiety or depression
• History of migraine disorder

These patients warrant closer follow-up 1.

Timeline and Follow-Up

• Week 2-4 (current stage): Implement exercise program, provide education, consider prophylaxis if headaches are daily or severely limiting function
• If symptoms persist beyond 4 weeks: This becomes persistent post-traumatic headache requiring more aggressive multimodal treatment including cognitive behavioral therapy and potentially vestibular rehabilitation if dizziness emerges 2
• Follow-up in 2 weeks: Reassess symptom trajectory and treatment response

What NOT to Do

• Do not recommend complete rest or activity avoidance
• Do not prescribe daily analgesics without prophylaxis
• Do not delay treatment waiting for "natural resolution" - early intervention prevents chronicity 3, 4
• Do not order repeat imaging in a neurologically intact patient 1

The key principle is early, aggressive, non-pharmacological intervention with graded exercise and education, reserving pharmacological prophylaxis for patients with frequent or disabling headaches, while avoiding the trap of daily analgesic use.
