I'll respectfully disagree with Chase1600. Lyme disease is endemic in the area where I live. Also, I got it and was initially asympotmic, hence untreated, and now it's chronic and seemingly incurable in my case. So you can be asymptomatic for months or become ill with flu-like symptoms almost immediately. Only about 50% of those with confirmed diagnosis report remembering having a rash. I did not. Testing for it is limited to antibody testing so testing immediately after a bite is worthless. It takes at least a month from the bite to get a positive test result.
Lyme disease is practically epidemic on the Eastern Shore of Maryland, where hundreds of thousands of deer harbor the deer tick whose bite causes Lyme disease. These tiny ticks are too small for many people to see; however, if you can't see them, you can feel them crawling on your body. One easily gets covered with them while hiking near woods or tall grass....even walking barefoot anywhere is asking for trouble, no matter where you are . Doctors here routinely test for Lyme disease among locals, since Lyme disease symptoms are so diverse: headaches, joint aches, heart palpitation, nausea , psychological problems, and on and on! Left untreated, Lyme can be very serious in its effect.
