If you experience any kind of pain in your elbows, knees, hips or other joints, I promise you, it's emotional. Heal that part, and physical pain heals itself. My favorite books that help me figure out what the hell is going on in my body are "The Secret Language of Your Body" by Inna Segal and "Your Body's Telling You: LOVE YOURSELF!" by Lise Bourbeau. They both give alphabetical insight to pain/disease within your body so you can HEAL YOURSELF.
