Chi (a.k.a. Ki, Qi, or Prana) is the life force energy that flows through every living thing. This is the force that gives you vitality and fullness of life. This is a fundamental concept of ancient Chinese medicinal practices. The idea is to keep your Chi energy flowing by maintaining a balance of Yin and Yang. When there is an imbalance and your Chi energy becomes stagnant or depleted you become susceptible to disease, illness and/or physical ailments.
In the metaphysical world, everything is connected, and when you are experiencing some sort of physical pain or discomfort there is typical a deeper root cause at your energetic, or Chi, level. There are several modalities that can bring your energy back in balance in your balance such as Reiki, Qi-Gong, Cranio-sacral Therapy, acupuncture, EFT (Emotional Freedom Technique), and others. Feel free to try any of these modalities out!
