Sorry to be so blunt, but it’s extremely unlikely both your sisters would have a rare chronic condition related to Lyme that wouldn’t respond to the standard course of antibiotics. The hysteria around Lyme on the internet is ridiculous.

Unfortunately nobody wants to say it to your face, but among females, you can never rule out social contagion when confronted with extremely coincidental outcomes like this.

Or, it could be a genetic condition they both have being misdiagnosed as chronic Lyme via internet research.
