Most doctors, even the urgent care ones, are pretty quick to notice signs of a tick borne infection. Doxycycline is the antibiotic of choice and is really effective. I have read a bunch of reports of lifelong problems associated with infection, and it seems to affect those that didn't get treated promptly. I have had RMSF about 3 times. Luckily, I knew what the signs were and went in for treatment. Lately, I have had what seem like relapses, where I have high undulating fevers, neck/joint aches, headaches, etc. If you have symptoms, go get it checked. Make them put you on doxy ASAP. The titers they run will take a little time, and may not show up positive, depending on the time and your bodies immune response.
