Late 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 knees3. 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.

Lingering symptoms after treatment (post-treatment Lyme disease syndrome)

Approximately 10-20% of patients with Lyme disease have symptoms that last months to years after treatment with antibiotics5. These symptoms can include muscle and joint pains, cognitive defects, sleep disturbance, or fatigue. The cause of these symptoms is not known, but there is no evidence that these symptoms are due to ongoing infection with B. burgdorferi. This condition is referred to as Post-treatment Lyme disease syndrome (PTLDS). There is some evidence that PTLDS is caused by an autoimmune response, in which a person's immune system continues to respond, doing damage to the body’s tissues, even after the infection has been cleared. Studies have shown that continuing antibiotic therapy is not helpful and can be harmful for persons with PTLDS.

I still wonder about that bite I had - arthritis, fatigue. cognitive defects. Maybe a vacation in Mexico can include a Lyme cure. There seems to be alot of Faith Based Diagnosis going on here, or Mythology Based ALZ diagnosis.
