Stress does not cause pain, but it can exacerbate it and make it worse. Much of chronic pain is 'remembered' pain. It's the constant firing of brain cells leading to a memory of pain that lasts, even though the bodily symptoms causing the pain are no longer there. The pain is residing because of the neurological connections in the brain itself.
