Lyme disease is a tick-borne disease with multiple organ failures, and systemic disorders. Dramatic change becomes apparent in the chronic phase of the disease. Chronic fatigue syndrome, lapse of concentration, depression, joint pain, and muscle pain are a few, but major clinical symptoms characterizing the disease. The human immune system is defenseless.Borreliauses various mechanisms to escape from immunoattacks or antibiotic therapies. This “stealth phenomenon” needs new therapeutic principles to be interrupted. Our objective in this paper is to study the effect of oncothermia, which is a well-established oncological therapy, on Lyme disease. First, in our present work, we definitely concentrate on the quality of life of the patients.
