How can the mind be used to lessen fear and pain during procedures?

Visual Imagery. Many times breathing techniques can allow you to relax quite abit. Other things that can help if you think of a quiet place or a place you would like to visit or even a favorite memory can be quite powerful by distracting your mind from the body's sensations. Meditation also is very helpful as well.
Perception. Change your perception when we anticipate negative things we fear if you change your view it changes your attitude.
