Oh you have Lyme disease? Here's 3 weeks of Doxy. The end.
That works if you start doxy within a week or so of the tick bite. Some people don't bother seeking medical treatment and keep on running, like I did. Now I have heart rhythm problems and postural orthostatic tachycardia syndrome as a result. Antibiotics can't fix that, nor did it clear the Lyme as I waited over a year before getting a Lyme test (tested positive twice from 2 different labs) so my body is riddled with it.
What kind of test specifically? Western blot? PCR? This is a lot more important than you probably think.
