Symptoms

Lyme disease occurs in stages, starting with early localized Lyme disease and progressing to early disseminated and then to late or chronic Lyme disease. The first symptom is usually a rash that appears a few days to a month after the bite. Up to 75% of those infected with Borrelia burgdorferi will develop the characteristic circular rash called erythema migrans. It typically grows outward from the bite site and lasts for several weeks. The rash may reach several inches in diameter and begin to look like a "bulls-eye." Some people may develop multiple red rashes and others may not have, or remember having, a rash.

  • Facial weakness and paralysis (Bell's palsy)
  • Numbness and pain in arms and legs
  • Meningitis, with neck stiffness and severe headaches
  • Chest pain and heart rate abnormalities (rare)
  • Eye irritation, redness, pain, and blurred vision (rare)
