Any suggestion given to you, while in the hypnotic state, will have an effect on you because it is impossible to separate the body from the mind. Therefore, they are dependent on each other. The mental element is always dominant and our physical organism is governed by it, so that we actually make or break our own health according to the ideas at work in our subconscious. We can freely implant whatever ideas we desire in the subconscious. Suggestion has always been and always will be the keystone to hypnosis, and it plays a significant role in nearly every aspect of medical treatment.
Pain begins and ends with the brain.
As long as we keep our mind distracted from the pain, it will be lessened. The major components of pain are stress, fear and anxiety, so people who suffer from chronic pain illnesses, which can be caused and or aggrevated from stress and anxiety, can decrease their pain with the power of the mind. For example, a group of people with chronic headaches were split into two groups. One group took hypnotherapy and the other group acted as a comparison group. The improvement isn't huge, but the results are impressing in such a difficult and hard to treat group of patients.
