My husband is in the hospital and is on delaudid for pain every four hours. He sleeps most of the time, does not want to eat (even though they are giving him something to increase his appetite), has cramps after a bowel movement, has burning when he urinates. When he is awake he is not coherent, he is very weak and can't walk without assistance. Could it be he is getting to much pain medication (oh, he is allergic to morphone).
