I recently attended a community event that featured various vendors displaying their craft.  I spent some time with a Doctor of Oriental Medicine who is also a Licensed Acupuncture Physician.  He indicated if a part of the body has pain when it is touched, that's an indication of congestion or too much energy in that part of the body.  If the body part has a tickle sensation when it is touched, that's an indication that the body part is depleted in energy.  Both situations call for a redistribution of the flow of energy throughout the body.  There are several techniques one can use to promote freer energy flow.  For instance, yoga, pranic breathing and exercises, meditation, acupressure points, Emotional Freedom Technique (EFT),  to name a few.  The idea that we store emotions in parts of the body has been proposed by a number of authors.  Louise L. Hay in her book You Can Heal Your Life has an extensive list correlating physical problems with probable causes.  Although these concepts are interesting, you should always consult your medical professional regarding any conditions you might have.
