A hernia in the groin, also called an inguinal hernia, occurs when part of the intestines, bowel, or other tissue protrude from the abdominal cavity and into the inguinal canal. This is not always painful, but pain and discomfort when coughing/sneezing, bearing down, lifting a heavy weight or having a bowel movement is common. Surgery is not always necessary and is generally only suggested if there is pain, discomfort, or an elevated risk for complications.
