I understand that the EM can reappear months after infection. However, I was never aware of an EM in the past, so if with an EM around a new tick bite, isn't it likely that there is a new infection?. My doc (can't get appt w/LLMD until Sept.) says, based on one lab test, this is not an active infection, but that I have had lyme in the past. I tried to persuade him to give me at least 6 weeks of Abx but he would only do 4.5 weeks of Doxy, 200mg 2x/d. If he thought it as an active infection he would have apparently given me more. I am taking several supplements and will be adding more very soon.
