what causes a lower right abdominal hernia?
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.
