4.2.1 Probable primary exercise headache

A 31-year-old CrossFit instructor has now had two of these attacks, both starting shortly after finishing an especially punishing workout of the day involving heavy barbell lifts and sprint intervals. He describes a sharp, gripping pain across the forehead, first noticed as he racks the final bar and worsening over the following half hour. The most recent episode lasted just over two days before settling completely, somewhat longer than the first. He denies any visual changes, vomiting or weakness accompanying either episode, and reports no other neurological complaint.
