I've performed mini-surgeries on animals quite a couple of times - like draining abscesses and cysts, sewing small wounds close, etc.
Todat I had to do this with myself. I cut a hole in my own flesh to remove a damned frucking ingrown infected hair.
Basically an ingrown hair is a hair that is growing UNDER your skin, instead of above it. They are usually very easy to remove as they are very shallow-located. It can turn to be very dangerous sometimes, too, though.
It's been there for almost 3 weeks. It started turning red and angry and was growing fast, so I just had to get rid of it as soon as possible.
Numbing cream, needle, a pair of scissors, tissues to wipe blood and TONS of patience and the fucker was out after almost 10 minutes of bloody work.
The bastard was hidden so deep I had to cut straight through the whole skin tissue and then dig in the flesh with pincette and needles, trying to spot the hair through the blood. How did it even get there?! But FINALLY it's gone! Even though the whole area around hurts like hell now, after all it's a deep, gaping hole.
Performing surgeries on others is much, MUCH different. Digging in your own madly bleeding flesh, chasing an ingrown hair is a whole another story
NEVER again I hope...Watch out for ingrown hairs, people! Never ignore them if they appear! They might turn into something much more nasty...
