A third type of groin hernia protrudes next to the blood vessels supplying the leg. This is called a femoral hernia, and is more common in women than in men.
Hernias may manifest themselves by causing signs and symptoms or by being discovered on physical examination. Symptoms may include pressure, tenderness or pain in the groin. There may be a gurgling sensation if there is bowel in the hernia. The classical sign of a hernia is a bulge in the groin. The bulge may appear spontaneously but is more common when straining. If a loop of bowel is trapped in a hernia the bowel may be obstructed resulting in abdominal distension, cramps, nausea and vomiting.

Hernias may also be asymptomatic and only discovered during examination by a doctor. The doctor examines for hernia by looking at the groin while the patient coughs to increase abdominal pressure. The doctor will then feel the groin as the patient coughs and will feel the external end of the inguinal canal by invaginating the skin of the scrotum on each side. If a doctor detects a hernia he or she will explain what a hernia is and why it should be repaired.
