Visualization, often called guided imagery, or creative visualization, is a powerful, natural way to deal with chronic pain. It involves imagining, in great detail, an ideal situation while experiencing the emotions that would emerge from that best-case-scenario.

So, if you’re feeling locked up in pain, you would imagine a vibrant, healthy, comfortable body and allow yourself to feel what that would be like. Stressed out about work? You could visualize your day flowing with ease.

This imagined scenario creates a real physiological response that can ease the stress that exacerbates pain and actually change the physical manifestation of it.
