Abcesses are collections of pus and infected tissue that can occur virtually anywhere in the body.
The ones I see tend to be superficial, meaning visible on the skin. They're red, swollen, and painful. And in general no fun to have.
And I love to lance them.
Really, a good I & D (incision and drainage) makes my day. There's something that takes you back to the satisfaction of being 13 and pressed up against the bathroom mirror squeezing that bad boy on your forehead for all it's worth.
They're not all fun and games. Sometimes you think you've got it and after torturing some poor soul with cutting and squeezing all you get is blood. Sometimes they are a real behemoth, unexpectedly, and you're not prepared for the overwhelming stench and fluid. Anaerobic bacteria really know how to turn on the fumes.
I'd probably tire of them if I saw them much more often than I do.
But the average primary care I & D, with no complications and a few CCs of pus...
It's really fun.
