I am the creator of the Yass method. This is the only method designed to properly identify the cause of pain. It will replace the use of the MRI as the primary method for diagnosing the cause of pain. It has been used over 2 decades to properly treat patients suffering with chronic pain. I have stopped thousands from getting unnecessary surgeries and treated thousands of others who had surgery that did nothing to resolve their symptoms. It is time to get your life back!
