What if one of the biggest reasons people stay stuck in chronic illness recovery is mold?

In this episode of Never Been Sicker, Michael Rubino sits down with integrative medicine practitioner Michelle McKeon to talk about the overlap between mold exposure, Lyme disease, mast cell activation syndrome (MCAS), long COVID, immune dysregulation, and personalized treatment.

Michelle shares why more patients today need customized care, how mold can suppress the immune system and complicate recovery, and why treatment order matters so much for sensitive people. Michael also explains why proper home investigation and remediation are essential if someone wants real, sustainable progress.

In this episode, they cover:
- Why mold is often a major missing piece in recovery
- The connection between mold, Lyme, and MCAS
- Why some people flare from supplements and detox protocols
- How long COVID and environmental exposure may overlap
- Why generalized testing and treatment often miss the full picture
- How personalized care can help sensitive patients move forward
If you’ve been dealing with mold illness, chronic inflammation, Lyme, long COVID, or MCAS, this episode connects many of the dots.
