I actually just cut a huge chunk of skin out of my ankle in the shower this morning. Luckily, my foot was underwater so it just felt like a sharp sting, but I remember looking at the razor, seeing a huge chunk of skin and thinking, "Eurgh, that's going to bleed a lot." The water got pretty murky within a few seconds so I just put my hand over it to stop it from bleeding, got out of the tub and galleons of blood dripped down my ankle and all over the floor. :< So, my granddad put some anaesthetic on it, cleaned it up and put a plaster over it but it STILL wouldn't stop bleeding (went, like, all over the kitchen floor) so he cleaned it up again and put a plaster on where it was leaking, then put a tight bandage on and a sock over it. It's been fine ever since.
And that's my in-detail account of my most recent injury. :3
