Into the Heart of Pain is an 85-minute documentary directed by Marc Wolfensberger, in collaboration with Marcel Schüpbach. The film explores the complexities of pain perception and management, delving into why individuals experience pain differently and whether we have mechanisms to modulate it. Through personal narratives, such as that of Patrice Dubosson, an agriculturist who returned to work shortly after a severe leg injury, and Mélanie Ammann, a professional dancer whose minor surgery led to chronic pain and depression, the documentary examines the disparities in pain endurance and the psychological and physiological factors influencing it. The film also questions the contemporary relevance of suffering and overcoming pain in an era of medical advancements.
