Thanks to both of you!
@limitgov: Thank you, I might try some of these Chinese herbs. Plus, they appear to be a good means of defense not only against borrelia, but against many types of pathogens.
@LeeO: Thanks for your detailed estimate!
Yes, the tick had grown quite considerably; I later learned that the risk for disease contagion increases dramatically once the tick has sucked for about 24 hours, which it probably did in my case. And yes, the rash was pretty much a textbook example of a Lyme disease indicator. I believe that I, too, was treated with Doxycycline.
Since I live in a traditional high-risk area for the two main tick-related conditions (Lyme and tick-borne encephalitis), local doctors appear to be quite educated on the subject (many have educational posters on the matter in their waiting rooms), so maybe that helped.
The symptoms of prolonged Lyme disease appear to be quite general, so I’m not sure I’m at risk even though I occasionally show some of them. I have, however, read that if no severe outbreak occurs for about 7-8 years after the last treatment, it is safe to say that there are no borrelia left. Would you agree with that statement?
And thanks again to both of you for your time and patience!
