I’m writing a novel and one of my characters gets stabbed in the lower region of the abdomen. I don’t want him to die or be incapacitated for a long time, so the wound can’t be too deep. The novel is set in a post-apocalyptic world so going to a hospital is not an option. What I want to know is: 1) How deep can the knife go without hitting anything vital?; 2) What do his friends need to do to help him (stop the bleeding, patch the wound…)?; 3) Would he be able to move/walk? Thanks in advance.
