what are the symptoms of sepsis in the elderly? My father in law is in his nineties and has dementia. He recently went on a brief trip with family and after the first day started to panic, stopped eating and drinking and became completely incontinent. He complains about suffering from constant bodily pain, so much so , that the 4 hour ride home- any bump in the road- seemed to torchure him. he s in bed now but not resting comfortably. Not sure whether he has a fever.
