Pain: There's a pain that's like, "I feel pain, but check it out right" The definition of pain changed over 40 years.

!---- There is a song called "Sadness is an unspeakable pain", so what is pain? Is it pain? Forty years later, the International Association for Pain Research has come up with a new definition: a sensory and emotional experience associated with actual or possible tissue damage or similar unpleasant ness.and the old definition of 1979 did not have the word "similar", adding it took 40 years.pain caused by previous tissue injuries, the new definition suggests that "I feel pain, but i'm fine" is also pain.this is common, if a person is in a doctor for pain, but all kinds of tests can not detect the lesions, the doctor feels no problem, but the person may be more anxious and continue to seek medical attention."Pain is a mentality that cannot be measured by external examination;old definition is also accused of "ignoring physical and mental interaction".the Expert Group believes that defining pain from the observer's point of view is controversial, and who has the right to judge that a person is in pain? The Panel concluded that whether it was doctors, patients, pharmaceutical companies, politicians, governments, lawyers or judges were "controversial" and should be the ones who suffered.pain is the nervous system's response to harmful stimuli.and pain is subjective and affected by life experience, loss of function, social factors and mental health. How dounderstand the new definition? The International Association for the Study of Pain gives six extended notes: pain is usually a personal feeling, affected by different degrees of physical, psychological and social factors; pain and injury perception are different phenomena, not only by sensory neuronal activity to infer pain, people through life experience to understand the concept of "pain", if a person tells of pain experience, should be cared for, although pain usually plays an adaptive role, but may have adverse effects on physical function, social and mental health; and verbal description is only a way of expressing pain, not being able to express pain.in fact, the so-called pain, is a complex physiological and psychological activities., on the one hand, includes the pain sensation caused by the harmful stimuli on the body, and the body's pain response to the harmful stimuli., on the other hand, should also include mental torture, adverse reactions to the perceived system.contains both sensory and mental pain. Who suffers more thanhumans than animals? The question is hard to say.but human beings are social, and people have more mental pain than animals, in addition to physical lying pain.from this point of view, sadness is really an indescribable pain. .
