Two weeks ago I sliced off a small piece of my thumb. My previous post about it and photos of it are here. I won't repost the photos here because they aren't all that pretty.
The instant I cut myself, I put direct pressure on the site. I then applied a plastic, waterproof bandaid with some tightness to maintain the pressure. I didn't find the flap of skin I had cut off until maybe 10 or 15 minutes later.
I didn't remove that bandaid for two days, at which time I washed the area, and that's when I took the photos that appeared in the earlier posting.
For the next week, I changed that bandaid every other day, but I kept the wound covered with slight pressure the whole time. Apparently it was good treatment, the right thing to do. Here is what it looks like today, two weeks later.
It has healed remarkably well and remarkably quickly. There will undoubtedly be a small scar there, but it won't be serious.
