AiArthritis diseases can be difficult enough to manage—but what happens when the symptoms don’t fit neatly into a diagnosis? In this episode, AiArthritis Health Education Manager Leila shares her perspective on the “mystery patient” experience, those living with serious, ongoing symptoms but still searching for answers.

Leila revisits key conversations from past episodes and introduces new resources, including our updated Mystery Patient Guide and the AUTO + Inflammatory Arthritis = X or YZ Project, which explores lesser-known or overlapping conditions like IgG4-related disease (IgG4-RD). She also shares the powerful story of a real mystery patient navigating the challenges of being undiagnosed for years.

If you or someone you love is living in diagnostic limbo, this episode offers validation, education, and practical tools to help guide your journey and highlights why improving awareness and research for this often-overlooked community is so essential.
