Getting illness and injuries 'right' on the page means doing a little research. I'll tell you how and where to start.
At some point in your story, your characters will almost certainly get sick or hurt. As Dennis Lehane taught me in my MFA program if you whisper brutality your readers will lean in to listen. But if you shout out gore, they will step back to avoid you. In other words, sprinkle on the injury description lightly, just a little spicy seasoning. but, make certain you get the injury description right -- because sure as hell one of your readers will have had that disease or injury.
Fortunately for writers (and patients), there is a plethora of medical informaiton out there on the Web. Not all of it is accurate. But, where do you start? I'll give you a few common sense suggestions:
- look into the landscape of your story: to determine what illneses or injuries 'fit'; for example, stories set in the northern climes might involve hypothermia or cold-induced soft tisse injuries. Tropics-based stories may see animal bites (snakes, monkey, etc.) or attacks (shark, lion, hippo, etc.) as a way to put your hero/heroine deeper in a hole.
- what risky activity does your character endulge in? common injuries can occur with many different sports and/or outdoor endeavors; you can scale the injury to the length of time you need your character out of action (off the storyline); a hand injury might keep your pianist from performing for months with all sorts of implications re career, practice, engagements, economics, etc.
- review your character's family history: do your heroine's mother, sister and two aunts have breast cancer? chances are there's a lousy gene in the attic (BRCA 1 and 2); inherited anemia? diabetes? Hypertension? There's nothing like a bad medical family history to set of a few ticking clocks!
- check out your character's workplace: ripped off finhgers, crushed legs, inhaled toxins can produce emerhgency room admissions or a slow degeneration fo a character's a bility ot see, hear, walk, etc.
I've advised novice, popular and literary authors in weaving believable medical threads into their stories.
