When I was in my early 20s, my arm became infected after being stung by a bee. That same evening, I suffered from tremendous itching and burning the likes I had never experienced. When I awoke, my entire forearm was ablaze in the color red. Recognizing that something was wrong I immediately rushed to the nearest walk-in clinic where the doctor who received me could not hide his shock.
His reaction was telling; if not treated soon and with the appropriate dose of antibiotics I could be in big trouble. He made me promise that I would adhere to the medication regimen. Further, he pulled out a big black magic marker and drew an outline around the infection. I was to visit him the next day at which time he could determine if the infection was still spreading or not. So joke — had the bacteria spread to other parts of my body and infect other regions, I may very well have died.
