Lyme disease is a multisystemic illness.

A different tick-borne infection than Lyme disease, babesiosis can be transmitted with the same tick bite.

The pain changes and moves around the body.

Another classic trait of Lyme disease is the migratory nature of the pain.

Your symptoms improve when you’re taking medication for other ailments.

Conversely, some individuals feel much worse on antibiotics, where all of their symptoms are intensified.

This is called aJarisch-Herxheimer reaction,4where the Lyme bacteria are being killed off, and temporarily worsen the underlying symptoms.
