Keep in mind, Lyme-infected ticks can be as small as a grain of sand. If symptoms persist or worsen, I suggest you see a Lyme-literate doctor (ILADS.org can help find one in your area) and be tested 'properly' for Lyme. Our family has battled Lyme for 5 years. The usual test in doctors' offices often comes back negative or etc .. and thanks to CDC is very antiquated. We were finally diagnosed thru IGENEX labs.
