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.
People suffering from intestinal obstruction may also experience lower right abdominal pain. This is a common condition that occurs as a result of lack of proper flow of liquids and food through the digestive system, therefore leading to intense pain in the lower right side of the abdomen.
