In this episode of Health Talk, Created to Heal, Dr. David Nelson is joined by Dr. Bill Kellis for a root-cause conversation about why symptoms often show up “downstream” of the real problem. They discuss how nerve irritation can trigger shingles flare-ups, why heavy metals may disrupt brain function and neurotransmitters, and how inflammation can be a signal—not the starting point. The conversation also covers practical sleep takeaways, including the role of electrolytes/minerals and strategies for staying asleep, plus a broader look at holistic foundations like clean water, dental health, and supporting the body’s natural ability to heal.
