Even small friendly (non-poisonous) spiders can be a problem. About 20 years ago, in late fall, I awoke to a painful wrist. Not far above the palm was the unmistakable pair of holes. A day later, time to see the doc because the redness, heat and burning was spreading. Cellulitis. Some AB's and all was fine.

But, every time after that, when I got a cut, hornet sting, whatever, I had issues with cellulitis infection. So, even a minor injury that bleeds must be taken care of immediately. I irrigate, blot and put isopropyl alcohol to it and bandage it. As soon as the bleeding has been stopped, I apply polysporin cream and a fresh bandage. Usually, within a day, I leave it open to the air.

Now, I was chastised by a buddy of mine for being a wimp. I ignored him and took the advice of my doc after having to visit him a second time after a hornet sting which became infected after I had to work under my truck in tha back woods in the mud. My doc drew a line about a half inch outside the visible infection with a pen and said, "If it gets near the line, go to the emerge." I asked why and he asked me, "Ever hear of necrotizing fasciitis ?" I answered yes but asked if it could really happen. He said, "Don't go to the emerge and find out."

I watched that wound for days.
