Several years ago, in Ardnamurchan, I was bitten by a large creature, which my Scottish mate called a cleg. It's bite was so big, the hole was clearly visible. I brushed it off mid bite. Within a few hours, the wound had swollen enormously. By that evening my whole calf was swollen and very noticeably bigger than the other, as well as losing any definition between calf and ankle. By the next day, the lower leg was still hot, red, swollen, and felt strangely hard to the touch. The the original wound site was still itchy. The leg remained this way for several days, before the swelling began to subside. It didn't stop me riding the bike, so I just ignored it, although it did look strange and scared small children. On my return to the Uk I had a GP appointment for another matter. My GP noticed the leg, which although much better, was still swollen, hard, red and hot to the touch. He asked me about it and I said it was just an insect bite and had been much worse. He asked me to describe it and then told me that if I ever had a reaction like that again, I should go straight to a doctor's as there is a chance of developing necrotising fasciitis from some creatures' bites. This, apparently, would be a Bad Thing.
I don't know if you have similar symptoms, but bear this in mind. Wouldn't want you to become necrotisingly fasciited.
