4.10 New daily persistent headache (NDPH)

A 36-year-old graphic designer reports a headache that has refused to resolve. She recalls a single, sharply defined attack that began one Sunday evening while watching television, a moment she describes in vivid, specific detail. She is consistent that the pain became relentless within a day of that evening and has remained present every single day since. She now dates the whole episode as running a shade past three months. The pain is left-sided, throbbing at times but mostly a dull pressure. She reports no associated nausea or vomiting, and no aura symptoms.
