Scientists are one step closer to understanding of chronic pain

According to the scientists, the probability of chronic pain depended on genetic factors by 50%, approximately. Also, the chronic pain of parents can affect the nervous system of the child in the early stages of development. In addition, the level of physical activity of parents and life in a stressful environment effected on the risk of chronic pain.

By the way, according to the scientists of the University of Colorado, opioid analgesics do not relieve from chronic pain. For five days the scientists gave morphine to rats suffering from of chronic pain. They have noted that pain tolerance has increased in the experimental animals. This effect lasted for three months.
