The United States has by far the largest correctional system in the world. It is so large, in fact, so sprawling and dispersed, so administratively complex that just how many people are incarcerated is uncertain. The most commonly cited statistic is that are about 2.3 million inmates on any given day.
Most often, a lump in the abdomen is caused by a hernia. An abdominal hernia occurs when there is a weak spot in the abdominal wall. This allows the internal organs to bulge through the muscles of the abdomen. A hernia may appear after you strain, or lift something heavy, or after a long period of coughing. Inguinal hernia appears as a bulge in the groin or scrotum.
There are a few possible causes of this type of pain. One would be an inguinal hernia. A hernia occurs when abdominal contents (fat or intestines) bulge through a defect in the abdominal wall, usually in a downward direction toward the scrotum. If the hernia is large, you should notice a bulge in or above the right side of your scrotum when you are lifting heavy weights or bearing down.
