I have got a nagging pain running up my giving-people-the-finger finger on my right hand. Near as I can figure, it is from using the trackpad on my MacBook.
Mindless, pointless stuff I must share.
Same injury, same hand, same digit, slightly more severe. Not even sure how it happened; I sure wasn’t flipping someone off. Well, I wasn’t!
Ice and Ibuprofen. And exercise that bird, believe it or not. I splinted mine for two weeks and just made it worse. 
Nah, I once had the stupidest injury ever. I was pulling staples out of a piece of wood, using pliers, and of course had my face right behind the pliers, so when the staple all of a sudden let go, POW. Had a jagged cut about an inch long zig-zagging through my eyebrow for a while.
Thank you, Burpo, in times like this, it gives me great solace to know I am not alone.
Max, do you still shudder at the sight of wood, staples, pliers? How did you deal with the psycho-social aspects of that facial disfigurement?
Same hand, same finger, reaching to give a small piece of meat to a cat above my left shoulder on the back of the couch. Cat gets overexcited, clamps down on the end of my finger while giving that “this is mine and stay the hell away from it” growl. Couldn’t twist around to try and pry the cat’s mouth open so I have to pull it out. Opens a gash across most of the length of the last joint of the finger.
Slack up some on the torque, Max. 
Is it stupider when you know it’s coming and you injure yourself anyway? Been there, done that, many times.
Well, there’s two kinds of stupid: injuries that shouldn’t be possible (like using the trackpad of a MacBook) and injuries that you should see coming but do it anyway. Strictly speaking, I think the former is a stupid injury and the latter is being stupid. And I have been stupid in this way many times! 
The track pad will eventually make your finger tip go numb. Is that really what you wanted?
Not-entirely unpredictable outcome of feeding an excitable carnivore meat using an appendage also made of meat. :eek: This is why I toss meaty bits (and treats of lesser meatiness) to my kitteh. She loves us, and would never hurt us, but “us” sometimes doesn’t include our fleshy attachments and extrusions.
RE OP, I had a similar swollen-joint injury in the same bird finger (mid joint, right middle finger). I’m sure it was right-mouse-button abuse when learning to play Heroes of the Storm. Stupid “15 games with a friend” promotion. Stupid “gotta get all the Warcraft mounts” completionist frenzy. The finger got better, but I’m done with any and all micro-management clickfest games from now on. I don’t need arthritis in a major finger of my dominant hand, dammit.
I’m sorry, but I don’t think so.
My brother was taking apart a fort he had built and had the wooden planks lying on the ground. When I was little, if I saw a plank I had to walk it pretending it was a balance beam. So I’m walking the plank and step on a nail. I squeal and pull the weight off that foot quickly and land on a different nail on my other foot.
And that is why I know the last time I had a tetanus booster :-S
All of which is why I’ve used a comfortable thumb-ball trackball (at ergonomic keyboard height) for decades. My arm stays mostly still with my wrist in an unstrained position, no fatigue or strain from “floating” my arm in a precise location in space, no finger aches from gripping a mouse. Allee samee for trackpads except that the hand fatigue comes from precise positioning and pressure of the fingers.
But yeah, I’ve had my stupid injuries. Too stupid to recount here. Okay, one: I was about ten, and walking across a friend’s yard towards where they were playing, and picked up a ping-pong paddle. I tossed it a few times to catch it by the handle, then flipped it way way way high in the air. And walked right under it, neatly catching it with the top of my head. No serious injury but I thought my friend’s mom was going to have a heart attack right there and then.
Not a problem limited to carnivores. Years earlier, I was attempting to feed and photograph a squirrel in a state park. I had the palm of my hand filled with Chex Mix (what I had handy at the time) and the squirrel was willing, but got nervous about having to reach way into my hand. and clamped down on a fingertip instead (also middle finger, but other hand.) I lifted my hand and the squirrel came up with it. I tried to get a photo of that, but unfortunately the squirrel let go before I got the shot.
There was also the time I was trying to feed an adolescent possum that I had captured (and had sitting in an old aquarium until I had a chance to drive it a few miles away and drop it at a riverbank) a piece of hot dog wiener by hand. Gave me a real good snap. This time the biter meant it, though.
So, now that I think about it, there is a lesson here, and the lesson is that I don’t learn from experience.
Nah, no lasting effects, not even a cool scar after it healed. While it was still visible and red, if anyone asked, I told them I was in a hockey fight.
Oh, bah!
Where did you hear this baloney?
When I was about ten, I found a wasp or yellowjacket drowning in our fish pond. I tender-heartedly caught it with a twig and was lifting it to safety when the twig flexed a little, depositing said bug on the back of my hand. Where it bit/stung me quite painfully.
I stomped the little shit and have never tried to rescue a venomous critter again.
There have been many over the years, but the most recent one was a couple of weeks ago.
I was taking apart my spiralizer to wash it when I accidentally sliced the tip if my right ring finger. Because I take bloodthinners to keep my blood from turning to jello, it bled for an hour and a half. I was this close () to having to put on pants and head to the ER (no way a bra was happening 
).
My wife got pecked in the eye by a chicken, which I maintain, is the stupidest injury ever!
What was she doing with the chicken?!
DH and I probably win this category. I have arthritis and he has fibromyalgia/bursitis/unspecific connective tissue “issues”. Stupid is when you pull a muscle toweling off after a shower or getting out of bed or reaching down to pick something up or turning your head to look at something. All of which has happened to either or both of us at various times. And we’re not even old yet. Technically.
Here’s mine. I was pulling cords out from behind my computer when one of them flew out with a lot more force than I was expecting and hit me across my eye, causing a laceration of the cornea. I had to use eye drops to prevent infection while it healed and walked around dripping tears for weeks.
