Patient Presentation:
Testicular pain

A 24-year-old male presented to the 40-mile aid station of a 50-mile trail-based ultramarathon. He reported acute onset of extreme left groin pain rendering him unable to continue. He required two-person assistance for a half mile up the mountain to reach the aid station. He believes the pain started when running downhill on a rocky portion of trail, but could not recall any specific injurious event. When he slowed to a walk, he hoped the pain would resolve spontaneously, however it worsened and had become nauseating.

He was a generally healthy, active male with no PMH to speak of apart from hamstring strains. He had previously worn compression shorts to help with these strains, but they caused significant irritation on longer trail runs. Therefore, he stopped wearing compressive gear over the last month of his training. He had no history of pelvic or testicular trauma, and denied history of hernia. He had urinated without difficulty within the last hour, and further review of systems was negative.
