Hi everyone,

MCU fanfic writer here! I need some advice on bruises and non-serious gym injuries/injuries from sparring or the like. Especially people with medical and/or martial arts backgrounds, please weigh in!

Character context: two non-superpowered hero characters (think Hawkeye or Black Widow), both are women, the injured character is in her early to mid-20s and has trained in different martial arts since she was a preteen

Scene context: It's basically a sex scene. Character A and B are long-distance and haven't seen each other in a while. Character A pulls up the other’s shirt and finds a fading bruise on her stomach. Character A asks about it. Character B replies that it’s a gym injury, because she got distracted during a kickboxing class. (The distraction was that she kept remembering a sex dream from the night before.) The moment is supposed to function as a brief interruption. It's basically 'not a big deal,' because they are both used to worse injuries, but it still makes character A pause, because like, Babe, why do you have a bruise I don't know about?

Injury details I've included: I described the bruise as “fading” and a “yellow-green mark.” It “hurt like a bitch” the first few days, but she can barely feel it now.

Timeframe-wise, I’m thinking the injury happened maybe two weeks ago, but I could change that. It’s not actually mentioned on page.

I have a feeling some of my details might be off? I did look up the different visual stages of bruises healing, but I have zero medical background, and all I know about kickboxing I learned from my google research.

So, my questions now are:

1. Does this injury make sense within the martial arts/kickboxing context? Is the bruising and pain level realistic? Or am I over- or underestimating it?

2. Does the timeframe make sense?

3. Would what I imagine as a kick to the stomach leave a bruise like that without causing more serious damage? Like, would the force necessary to leave a bruise also cause other injuries?

If this combo of injury and cause of injury doesn’t work, I’d also love to hear alternative suggestions if you have any!

Of course, this is Marvel, so there’s some major leeway since we repeatedly see characters without superpowers be kicked or fall from questionable heights and get back up again. But I really like to have my medical facts be as accurate as possible. (And if I feel the need to deviate, I at least want to know the factual realities I’m intentionally deviating from.)
