Which is the best techniques?

Whatever pain relief technique is used – operant conditioning, biofeedback, relaxation, or some other – success greatly depends in the patient’s conviction that the pain can in fact be controlled. This brings us back to the importance of an internal locus of control. Without this feeling of control, the effectiveness of any pain control method will be substantially reduced. Over half of patients achieved at least a 33 percent reduction in pain through biofeedback and hypnosis, attributed the success of their program to four factors: distraction of attention, suggestions, relaxation, and the sense of control over the pain.
