DON'T BE AFFRAID OF TREATING YOURSELF

Super glue works great for closing wounds up. I don't indorse it being used INSIDE an open wound under the skin. It dries funny in open wounds and actually forms tiny flat sharp edges that can cut you up once the wound is closed. Topical application only. There are medical grade silicon and other types of adhesives but the average joe wont have access to these.

I prefer a few wound closure strips and then apply the superglu to keep the area free of dirt. Yes, as with any wound, if you don't clean it well, you will get debris/ bacteria trapped under the skin. The trick is to clean better than you think you have to alcohol, Iodine, alcohol, Iodine working your way out from the center of the wound- a clean applicator at each step. Letting a nasty dirty wound bleed for a little (as long as you aren't bleeding to death) is a good thing also.

Or if you choose to learn how to suture wounds and do this, a drop of Supergle on each knot protects them from unravelling. This is all basic firstaid on the small scale though. Things change when you start talking major injury.

Ironically, on a trip with a doc and his wife and some buddies we were climbing a razor wire fence to access a killer climbing spot and the wife cut her hand pretty bad. I was the only one with a first aid kit and the only one that stepped up to treat her. Sat her down, calmed her down, cleaned it very well and then the old wound closure strips and superglu. My nitrile exam glove came off my hand and then inside out on to hers and I athletic taped it on. She was able to climb the rest of the trip with no worries, and wore her scare like a badge of honor.
