Chris Williamson just opened up about one of the heaviest things he's gone through. He flew to Vienna for an intense experimental treatment: extracorporeal blood filtration combined with whole-body hyperthermia (raising his core temperature to 41°C / 105°F) and oxygenation. They ran his entire blood volume through a filter roughly 15 times over several hours while under anesthesia, aiming to pull out toxins and hit deep intracellular infections like chronic Epstein-Barr, CMV, and Borrelia that hide inside cells and drain mitochondrial energy. Therapeutic hyperthermia (controlled fever) has been studied for decades because many pathogens, including Borrelia (Lyme) and certain viruses, are heat-sensitive. At temperatures around 41°C, they become stressed, release toxins, and become more vulnerable, while oxygen-rich blood can help combat intracellular infections and support mitochondrial function. The filtration step then removes the dumped toxins and inflammatory mediators. Day three was mostly recovery and reset, but Chris is honest about how brutal the whole process feels — the physical pain, the loss of control, the emotional weight, and the patience required when progress is slow and uncertain. He's still fighting, still hoping this brings him back to himself. Respect for putting it all out there so openly. What’s the hardest part of health journeys for you — the physical toll, the uncertainty, or learning to be patient and gentle with yourself when nothing feels in your control?
