DEAR DOCTOR K: My neighbor was diagnosed with Lyme disease. Why does he still have symptoms, even though he has completed his treatment?
DEAR READER: The great majority of people diagnosed with Lyme disease, and properly treated, are cured. However, there are some people like your neighbor, who are never fully cured, and we do not understand why proper diagnosis and treatment does not always lead to the elimination of suffering. Here's what we do know. Lyme disease is an infection caused by bacteria that are transmitted through tick bites.
