                                                          The itchyness of a rash is not the characteristic that gives it away that it is lyme disease.  The characterisitic feature is called erythema migrans, or the fact that it is a taretoid looking lesion.  Regardless, if you are worried about lyme you should see you doctor as it is treatable.
