Differential Diagnoses:

1. Cervicogenic Headache – Likely due to cervical spine dysfunction post-whiplash and muscular strain.
2. Tension-Type Headache – May be exacerbated by ergonomic strain and prolonged screen time.
3. Ocular Strain – Due to farsightedness and prolonged computer use.
4. Postural Syndrome – Muscular overuse and imbalance from extended sedentary activity.
5. Cardiovascular Etiology – Given the family history and episodic intensity, further evaluation is warranted.
