Dude this is industry swill. There is absolutely no evidence for "post Lyme syndrome" done by any legitimate (read: non insurance backed) research team.

Proof?

Check the study where ticks are introduced into a room with post Lyme patients. Spoiler: ticks bite post Lyme patients and end testing positive with Lyme disease.

Conclusion? Post Lyme is Lyme, insurance companies are on the hook for billions if they gave to cover that... So. Yeah. There is incentive to not do that.
