Cath surgery

Did anyone have lots of pain after their abdominal or presternal cath surgery? My dad had a presternal cath implanted yesterday and his having lots of pain in his abdomen where they went in but not in his chest where the exit site is. He has been in bed since yesterday but is eating small amounts of food and drinking okay. Has not been nauseated or vomitted. My mom says he is urinating well but kinda of constipated. So she gave him a laxative and he went a little. When should we make him get up? I know its not good to lay in bed but I know he cant feel well with his kidneys and now surgery. Thanks for any help.
