How it's used
This idiom describes someone who gains extensive knowledge about a specific medical condition or treatment simply through the experience of suffering from it for a long period. It is often used to describe patients who have become so familiar with their symptoms and treatments that they can manage their own care without constant medical intervention. While it implies a high level of practical knowledge, it does not suggest formal medical training or professional qualifications.
