Physical Pain May Worsen With Stress

Acute psychosocial stress reduces the body’s ability to modulate physical pain. There is a Hindu story about the goddess Cholera. (Hindu's perceive everything as God, and give physical characteristics to people, diseases -cholera, etc.). A man passes the goddess on the road, and says to her, "I hear you killed 100 people in the last village." And she responds, "I only killed 10 - the others all died from fear."

We have long known the many negative effects of stress. Worry about a normal headache, and suddenly it becomes a brain tumor.

Stress is defined as a sense of uncontrollability and unpredictability, and is often the cause of a variety of negative personal, as well as social, effects. Ruth Defrin, from Tel Aviv University (Israel), and colleagues enrolled 29 healthy men in a study in which the subjects underwent several commonly accepted pain tests to measure their heat-pain thresholds and pain inhibition, among other factors.

Participants underwent a series of pain tests before and immediately after exposure to the Montreal Imaging Stress Task (MIST), a computer program of timed arithmetic exercises, designed to induce acute psychosocial stress.  MIST provides live feedback on submitted responses, registering only 20-45% of the responses as correct, whether or not a submitted response is the right answer. Because the subject has been previously informed that the average participant tends to score 80%-90%, he is reminded of his "poor performance" but has no way of improving his score, despite his best efforts. This provides the "stress" element of the experiment.

To further test the effect of stress on pain, the team divided the group according to stress levels.  The investigators found that not only does psychosocial stress reduce the ability to modulate pain, the changes were significantly more robust among subjects with stronger reaction to stress ('high responders'). The higher the perceived stress, the more dysfunctional the pain modulation capabilities became. In other words, the type of stress and magnitude of its appraisal determine its interaction with the pain system. 

Observing that: “acute psychosocial stress seems not to affect the sensitivity to pain, [but] it significantly reduces the ability to modulate pain in a dose-response manner.,” the study authors submit that: “it appears that the type of stress and the magnitude of its appraisal determine its interactions with the pain system.”

In other words, if we have physical pain, it becomes worse the more we worry about it. Reducing stress should be a priority in our everyday living. In my opinion, the best way to do this is meditation, and learning fortitude - accepting the things we cannot change, and just not worrying about them.
