Lyme disease exposes how overrated medicine is. People have come to expect modern science to be able to detect and cure bacterial infections, at the very least — and yet for Lyme, a bacterial disease transmitted by ticks, the tests are shockingly inaccurate, and antibiotic treatment doesn't always take away the often debilitating symptoms like joint pain, fatigue, brain fog and headaches.

Some doctors admit they aren't sure of the answer.

Others, self-styled "Lyme literate" doctors, are stepping into the void, often diagnosing based on weak evidence and exposing patients to months or years of potentially harmful antibiotic therapies.
