I have diverticulitis w frequent abdominal pain but this time pain is severe and keeps moving all over abdomen.also had bruised kidney 1 mo ago

Diverticulitis: Your age is not stated & it is unclear if correct terminology is being used diverticulosis vs diverticulitis. Generally after 2-3 episodes of severe diverticulitis (inflammation of a diverticulum) surgery is considered. For recurring pain associated with having diverticulosis but no evidence of fever, chills, elevated white blood cell count & pain(diverticulitis) management is medical. See your md.

See your doctor ASAP: If you are having 'another diverticulitis attack' you need to see your doctor/surgeon ASAP or even go to the Emergency Department. Frequent attacks is an indication for surgical resection of the offending part of the colon (usually the sigmoid colon.)
