Woman's crushing headache took years to diagnose

The 44-year-old legal assistant at a Northern Virginia law firm had been working out with a personal trainer at her gym, executing a demanding and unfamiliar move. As she pulled down on a bar equipped with weights while simultaneously lunging forward, she felt an explosive pop in her head, immediately followed by a headache more crushing than any she had previously experienced.

For the next 10 minutes, White recalled, she sat on the floor, clutching her head and fearing she would throw up or pass out.
