I just posted a response to your injury and came across this one. I'm an old hand at ticks. I'm surprised you ran into one this late in the summer. Most ticks are not the carriers; just a creepy source of itch. When detaching one get the whole body with a tweezer and pull it off head and all. I flush the little buggers down the toilet so it won't reappear some how as they are very hard to kill.
