Just for future reference - when you pull off a tick, grasp the body and head with tweezers or a hemostat and twist. The twist 'unlocks' the mouth/teeth and makes it for a cleaner removal. You always need to make sure you have the head. If left behind it will become quickly infected and get really bad, really fast.
Unfortunately, living in the middle of nowhere means LOTS of ticks and their season is from March to about the end of October around here. With the 'high' season is June to September. The first year we were here, we found a live tick on DH's leg right before Thanksgiving, but it had been really wet and mild. Can't wait for the first frostfreeze to kill 90% of all of the nasties outside.
