Occurs when tissue pushes through a weak spot in the groin muscle. This causes a bulge in the groin or scrotum. The bulge may hurt or burn. The hernia may get larger with straining. If the bulge does not go away with relaxation it can become lodged in the defect (an incarcerated hernia). Intestine can become trapped in the hernia and lose its blood supply leading to a serious surgical emergency named strangulation.
