At ACU4U, one of the most common problems that our visitors suffer from is chronic pain. An analysis funded by the National Institutes of Health’s National Center for Complementary and Integrative Health (NCCIH) and published in The Journal of Pain (2010) indicated that an estimated 25.3 million adults (11.2%) experience chronic pain and nearly 40 million adults (17.6 %) experience severe levels of pain¹.  Chronic pain --- from headache, low back pain, joints pain, neurologic pain to cancer pain --- represents a major clinical, social and economic problem. The impact of pain on economies is enormous, with the cost of back pain alone equivalent to more than a fifth of one country's total health expenditure.
