Feeling in the area of damage detected by the nociceptors present in the abdominal cavity and on the organs it doesn't have a sharp onset visceral pain [8]. This effect is also termed as viscero-somatic convergence where the pain signal transported by afferent nerves converge with the nerves that are transferring pain from the say skin area can cause side effects such as nausea vomiting etc. [12].
