Dr. David Musnick, MD, IFMCP

David Musnick is a board-certified medical doctor who offers in-person and telemedicine care from the Functional Medicine of Idaho Eagle clinic. Dr. Musnick offers Functional Medicine, Sports Medicine, Functional Immunology, and Primary Care for adults and teenagers. He specializes in sports medicine, internal medicine, frequency specific microcurrent (FSM), scars, homeopathy, prolotherapy, and low-level laser treatments.

Dr. Musnick is interested in getting to the root of underlying causes and factors that affect healing, including diet, sleep, exercise, stress, mood, GI health, brain region health, toxins, mold, hormones, infections, and electromagnetic fields (EMF). He is excellent at Orthopedic diagnosis trying to determine which tissues are causing pain, what the issue with the tissue is and what is going on in the pain processing system. He has developed a unique program to heal the brain after Concussion that is based on what actually goes on in the brain after head injury. His program integrates: diet, supplements, sleep, exercise and microcurrent and brain training to heal the brain after concussion. He also applies this to other brain based disorders including cognitive impairment and dementia. He has a special interest in autoimmune disorders and has studied Functional Immunology. He is one of the top 10 clinicians in the world with Frequency Specific Microcurrent and he teaches at Microcurrent meetings. He is also very experienced in Prolotherapy regenerative injections to build more ligament to stabilize a joint or area of the spine.

In medical school, Dr. Musnick spent a year studying nutrition. He has always been interested in the complex interrelationships of different systems of the body. Taking on challenges in the past, he created new treatment programs to heal the brain after concussion, treat chronic pain, arthritis, and tough SIBO and IBS cases. Dr. Musnick wants to help his patients achieve the highest level of health, vitality and function.

After his internal medicine residency in Seattle, Dr. Musnick completed a fellowship in sports medicine where he became interested in helping patients get back to optimal musculoskeletal health and eventually back to their favorite activities. He quickly learned that many areas of the body were interrelated and started learning more about nutrition, supplements, and other facets of functional medicine. Dr. Musnick has more than 24 years of experience in Functional Medicine and achieved a very high level of both experience and expertise with many health conditions. He is also the author of the book, Conditioning for Outdoor Fitness, and helped in writing textbook chapters on arthritis and concussions.

Dr. Musnick received his Doctorate of Medicine from the University of California, San Francisco. He is certified through the Institute for Functional Medicine as an IFMCP. He also studied in the French school of Homeopathy. He is uniquely rare in that he teaches Frequency Specific Microcurrent (FSM) and how to integrate it with functional medicine.

In his spare time, Dr. Musnick enjoys hiking, nature photography, cooking healthy food, mountain biking, and skiing.
