The human body is a big repository of repressed emotions, which are stored in our subconscious waiting for us to deal with them. When no special attention is paid to them, they start manifesting as physical symptoms: tension, headaches, pain, cancer, etc. Those emotions could have very well generated in this life or a previous one.
Introspective Hypnosis is a technique for the treatment of psychological disorders such as phobias, fears, sorrows, anorexia, bulimia, low self esteem, insecurity, migraine, obesity, obsessions, quit smoking, obesity and allergies. It is also used in medicine and dentistry for pain suppression. Using hypnosis we get access to a person's subconscious and go to the origin of those psychosomatic symptom. Once we understand the psychological or emotional origin and deal with it, the symptom disappears.
