I'm currently writing an apocalypse themed story. As with the territory, death and/or injuries happen. I'm wondering how other writers write these scenes realistically as far as science, medicine, and biology are concerned?
Meaning, if I injure a character's eye, knowing what happens if I do that, what methods can be used on the injured character when there is no sufficient medical expertise available, or the consequences of not having that medical treatment. Do writers just go by reading other materials of the same theme, looking into medical articles? I'm not really sure where to go to research this.
Google doesn't seem to be sufficient because if I look up an injury, it's going to tell me, "Seek medical attention" on some medical site and well, if this is the end of the world, what's going to happen to this character who can't seek this medical attention?
Thanks in advance for any resources or tips. :-)
