This episode of On One Condition follows Jenny Trefzger’s journey through persistent abdominal and groin pain after surviving stage IV colon cancer.

After years of scans, colonoscopies, PET imaging, blood tests, spine evaluations, pain procedures, and repeated reassurances that cancer had not returned, Jenny eventually encountered the possibility of Anterior Cutaneous Nerve Entrapment Syndrome (ACNES), a frequently overlooked cause of chronic abdominal wall pain.

The conversation explores the emotional burden of living with a cancer history, the challenge of distinguishing new symptoms from recurrence anxiety, and the importance of hands-on examination, self-advocacy, and specialist expertise.

Despite a long and frustrating diagnostic journey, Jenny is optimistic that she has found the right team who will be able to treat her chronic pain.

The song that Jenny chose is At The Limit by Yuki Hayashi.

This episode is both about Carolina and her daughter Mariana’s journey with Pfeiffer Syndrome, and about how rare disease families can truly impact healthcare.

Carolina shares the long and emotionally exhausting path to diagnosis, the repeated hospitalizations and surgeries Mariana endured, and the emotional impact of raising a child with a visible rare disease.

What stands out throughout the conversation is Carolina’s extraordinary resilience and compassion. Rather than allowing fear and trauma to define their lives, she transformed her family’s experience into advocacy, education, and systemic change through the organizations she founded, including Born a Hero.

The episode explores difficult but important topics: medical gaslighting, delayed diagnosis, the emotional toll on caregivers, bullying, mental health, and the urgent need for patient-centred healthcare. Yet despite the challenges, the conversation is filled with hope, warmth, and humanity. Carolina repeatedly returns to the power of kindness, collaboration, community, and listening to patients and families.

It is ultimately a story about turning pain into purpose, and about how rare disease families often become the strongest advocates, educators, and changemakers.

The song that Carolina chose is The Truth by Megan Woods.

This conversation is a reminder that rare disease stories are not only about struggle — they are about resilience, discovery, community, and hope. Melissa speaks beautifully about seeing beyond limitations, recognising Taylor’s intelligence and individuality, and finding meaning through her work with the Pura Syndrome Foundation.

It is a moving episode about motherhood, purpose, and the extraordinary strength that grows from love.

The song that Melissa chose is Blessings by Laura Story.
