Those things are definitely nasty. My buddy that I play softball with got bit by one a few summers ago and the same thing happened - the wound ended up being the size of a silver dollar and they had to do some minor surgery and stitch him all back up. Even as it was healing it was nasty.

I'm sorry to hear what you had to go through, but glad they were able to take care of it. Good luck and be careful out there!
