What Causes Stabbing Pain in the Navel Area?

Stabbing pain in the navel area is known as pelvic pain, and it has multiple causes. Abdominal pain below the belly button can be harmless, such as PMS, also known as premenstrual syndrome, or a sign of fertility; however, the pain might be something far more serious, such as a life-threatening condition, according to WebMD. Belly pain and cramps generally accompany digestive disorders, such as irritable bowel syndrome.
