because certain injuries simply don't match claims of how they occurred.

My husband once tried to lie to a doctor about how he broke his hand. He did it punching a wooden kitchen cabinet because we were having a huge fight and he was so angry at me for something he believed I'd done, but hadn't. I was laughing at his ridiculous accusation, which infuriated him. He didn't want to hit me so he turned around and slammed the cabinet, leaving knuckle imprints because the wood had no give. Badly broken hand resulted.

The fight ended immediately as I got ice packs and called his brother to come over to stay with our kids who were sound asleep upstairs so we could get him to the ER.

The highly charged emotions during the stupid argument quickly changed to absurd laughter about the whole thing. It was totally ridiculous and his OTT reaction quite shocking. We kept making more and more jokes about how stupid it all was, going off on crazy tangents. We were still laughing when we got to the ER.

He'd had what he calls a shot plus a beer beforehand so was slightly buzzed and very embarrassed at losing his cool like that, along with punching the cabinet. I was a little bit high but hadn't been drinking so I drove.

So anyway, he lied about how it happened, claiming that he'd been trying to change the ring under the toilet to stop a leak (which he had done the day before) when it fell onto his hand (which never happened) because he didn't want to admit how angry he'd gotten.

Still amused about the absurdity of it all, and how funny he was on the way there, I fell off my chair laughing so hard when he claimed something so unexpected with a straight face, spinning a silly tale about how it happened and never even cracking a smile as he told it.

Of course, the doc could smell alcohol on him and assumed we were both quite drunk. She was quite cold to him and quite brutal about setting his hand and making a cast. She refused to give him any pain meds as she pushed hard on his hand to put his knuckles back where they belonged because she said pain meds mixed with alcohol was too dangerous. She didn't believe that he wasn't falling down drunk because of how we were both reacting. I can't say I blame her, considering.

Plus, she knew he was lying about how it happened.

The kind of damage done by something heavy falling onto your hand, crushing it is radically different than the kind of injury caused by punching something solid.

Just like the kind of injuries caused by beating someone up vs a person running face first into a wall by themselves. Not even remotely similar.
