Symptoms of inguinal hernias in boys are a bulge where the thigh and groin meet, swelling and pain in the scrotum, and pain when coughing, bending over or lifting objects, according to KidsHealth. Boys with epigastric hernias may see a lump somewhere between the belly button and chest. Hiatal hernias do not have visible symptoms, but people may experience heart burn, indigestion and chest pain.
In boys, the location of the inguinal canal is between the abdomen and the scrotum. A defect in the canal where the intestine is able to slide into the canal is usually the cause of an inguinal hernia, notes KidsHealth. This type of hernia is the most common and requires surgery as treatment. It is more likely to occur in boys than girls. Other symptoms include heaviness or burning in the scrotum or inner thigh, and nausea or vomiting if the intestine is stuck, states WebMD.
Approximately 75 percent of epigastric hernia cases occur in boys. This type of hernia occurs when the intestines jut out through the abdominal muscles, and surgery is a common treatment, explains KidsHealth. Small hiatal hernias may not produce any symptoms at all. They occur where the esophagus meets the stomach.
