Psychogenic pain occurs when the mechanism of injury-receptive pain or neuropathic pain is not present, but there are sufficient psychiatric symptoms to meet the diagnostic criteria of somatic pain and depression. Some diseases caused by non-organic damage can occur as pain despite the fact that the organs in question are intact. This type of pain is caused purely by psychological factors or psychological disorders, and we call it psychogenic pain. The main psychological pains are as follows: 1. Hallucinatory pain: there are often hallucinations. If the patient feels that he is controlled by some kind of electric wave, he has frequent chest pain and discomfort, accompanied by the feeling of electric wave irritation. However, after repeated examinations, the doctors could not find any organic lesion. This kind of patients with general pain medication is not effective, because their pain is one of the symptoms of psychosis, so they must use antipsychotic drugs, in order to achieve the effect of “pain relief”. 2, anxiety pain: caused by excessive anxiety. The symptoms can be relieved by taking anti-anxiety medication and diversion therapy. 3, hysteria: the so-called “hysteria”. This type of patient often has some psychosocial factors, and attempts to use pain to avoid things that are not good for them, in order to obtain sympathy or support. For example, one patient felt sharp pain in the head, neck and precordial region, and occasionally a dull pain. However, after detailed examination, no organic injury or disease was seen; considering the site of his pain, which was also not distributed according to the anatomical features of the nervous system, he was diagnosed with hysteria. Under the psychological hypnosis of the doctor, the psychosocial factors were found and the symptoms were relieved by giving suggestion therapy and relieving the psychological factors. 4, depression: this type of patients, a number of people always feel that there is something wrong with them, but can not find out, but do not believe that they are not sick. Over time, more symptoms of suspicion appear, and then depression occurs. And clinical work, doctors have found that the vast majority of depressed patients have pain symptoms.
