I caught Lyme earlier this year. Recently moved to upstate NY (20 miles from Lyme, CT) and tick checks are a daily thing. Found an adult embedded in my side. Developed a 103ºF fever and fatigue. Dr. took blood for the Lyme test but didn't wait for a positive and prescribed 2 weeks of Doxycycline.
A few days later I found a bullseye rash on my leg (not near the bite area) which pretty much confirmed it.
I felt 100% around 5-7 days after developing fever symptoms.
