You are never disconnected at the neck.
What happens in your mind- emotions, thought processes, perceptions and your five senses- is always reflected in your body. In the same way- what happens in your body is also always reflected and recorded in your mind.
Consider the communication between your mind and your body as being part of a triangle. The top of the triangle can be thought of as your brain, the conscious mind; then, on the left-hand side of the base you have the subconscious, and on the right-hand side, your body.
Communication occurs along all sides of this triangle. All are important, but the most important is the communication across the base, the subconscious- body connection. It is this connection that we work with using hypnosis.
Communication goes all ways. There are no one-way streets- only sharing of information, communication, back and forth, along all sides of the triangle. Conscious, thinking mind; subconscious, emotional mind; perceiving, experiencing body!
It is through this mind- body communication that we can work towards achieving the healing you are seeking.
