Lyme disease is the result of an infection in which the Borrelia burgdorferi bacteria travels into your bloodstream from the bite of an infected tick. This type of infection can cause fever, headache, fatigue, and a skin rash. If not treated properly, the infection can spread to your joints, nervous system, and heart.
In neurological Lyme disease, your symptoms could be primarily neurological, making it difficult to perform your usual tasks or your job.
