I got shin splints after using the leg press machine at the gym. Lifting far too heavy, far too quickly.
It was surprisingly painful, especially going down any stairs or slight slope. I was mid 20s at the time and hobbling around for a good week or so.
Also nearly cut the end of my finger tip off whilst cutting a frozen bun. Luckily, it didn’t go all the way through, but I needed stitches and have a cool little scar now.
