I was exposed to ticks about a month ago and later removed four which had attached. One (behind my knee) was engorged, and about 10 days later the bullseye rash appeared around that one. The doc immediately put me on the 21 day cycle of doxy, but the test came back negative (I'm pretty sure it was a false negative because of the rash). I'll finish the doxy in two more days, but the sites of the four bites are still itching! It comes and goes, and they are still raised and purplish-red. I could go on about other symptoms (fatigue and a brief spell of sore lymph nodes in my neck, among others), but I could also attribute that to possible cold/allergy, or side-effects of the doxy...(?). I don't have health insurance, so I can't just run to the doctor with each concern. I guess my main concern at this moment is the continued itching, especially after an almost complete course of doxycycline. But then, I also wonder if the treatment is effective, can symptoms still be occurring as the residuals of the infection continue to clear out after the med is finished?
