I had a similar experience last season. I was in a state of panic, but the doctor told me not to worry unless I started experiencing Flu-like symptoms. so, I would say not too worry too much about it unless you start feeling bad in a few days.

The gotcha is, if you're gonna get Lyme, it's too late to torture yourself by cutting off portions of your body; the bad juju is already in your system. And, it stays there forever. Just see your doctor if you start feeling bad and get some antibiotics and you'll be fine.
