I take care of a gentleman, 87, who was in a car accident last week Tuesday. He turned in front of an oncoming car and was hit in the rear passanger door hard enough to deploy the airbag. He had no visible injuries and refused to go to the hospital. Later that evening I took him to Urgent care to be looked over. He was given a clean bill of health and sent home.
Today he is pale and has had black loose stool and just doesn't feel well. No tenderness in his belly, no bruising, soft to the touch. Serious or not?
