After 40 days of ground parachute training, there was no obvious reason for a mass in the left groin area, which was oval and sometimes into the scrotum without obvious discomfort. Often when the training intensity appears large, disappeared when lying or rest, no similar history. Half a month later, the bump suddenly increased during the continuous high-intensity jerking and landing training
