Arthritis caused by Lyme diseaseLate disseminated stage (months-to-years post-tick bite)
Approximately 60% of patients with untreated infection may begin to have intermittent bouts of arthritis, with severe joint pain
and swelling. Large joints are most often affected, particularly the knees. Arthritis caused by Lyme disease manifests differently
than other causes of arthritis and must be distinguished from arthralgias (pain, but not swelling, in joints).
Up to 5% of untreated patients may develop chronic neurological complaints months to years after infection4. These include shooting
pains, numbness or tingling in the hands or feet, and problems with short-term memory.
