Visceral pain comes from internal organs that contain visceral nociceptors sensitive to distension, ischemia, or chemical irritation. The sensory signals travel with autonomic nerves to the spinal cord, producing a diffuse, poorly localized sensation that can be felt far from the actual organ (referred pain). This contrasts with somatic pain from the skin, bones, or peripheral nerves in limbs, which is usually well localized and sharp. So the typical source of visceral pain is internal organs such as the abdomen or gallbladder.
