What can happen if I ignore a hernia at the groin area without treatment or surgery?

Hernia. Hernia repair is always recommended, risk/benefit analysis favors repair. However, it is elective outpatient procedure when healthy and not having symptoms (no er visits), okay to visit surgeon, get monitored. Elective scheduling with monitoring, can be 6 to 12 months out. Be well.
Inguinal Hernia. Increasing pain, increasing risk that your intestine will drop into your scrotum and cause death or permanent damage to the testicles leading to no testosterone.
