1.5 Probable migraine

This was her first, and so far the only, presentation of this kind, occurring three days ago while she was at work. She described a sudden, fizzing tingling that appeared abruptly, without any slow crescendo, spreading up from her fingertips into her forearm; it was, she said, the only strange sensation she noticed, with nothing else joining it, and she could not say it favoured one side of her head over the other. The tingling itself lasted around forty-nine minutes by the clock on her phone. A pounding head pain arrived within the hour, while the pins-and-needles were still fading. She denies any sickness, denies any sensitivity to light, and has not vomited at any point.
