Tumor patients suddenly develop intolerable pain, i.e. burst pain, which is often paroxysmal and usually lasts for about 30 minutes. When the tumor patient has sudden onset of pain, it will be accompanied by other symptoms. At this time, we can examine the patients with fulminant pain according to the clinical symptoms. Examination of clinical symptoms of fulminant pain: 1. Accompanied by strong phytoneurological abnormality In most patients, the response to persistent pain is phytoneurological, and the patient is mentally and physically withdrawn and appears to be depressed. In some patients anxiety predominates, or anxiety mixed with depression is present at the same time. In all cases of unstoppable pain, there is a vicious circle of “insomnia → fatigue → pain → insomnia”. Psychological abnormalities should be evaluated and initial psychological support should be provided at the time of diagnosis. When anxiety is prominent, treatment should include analgesics and anxiolytics, with the choice and dosage of each drug largely determined by what the patient has taken before. Unstoppable pain with significant anxiety is best viewed as an emergency and requires a significant amount of time to treat it. Ideally, an experienced physician should be in charge of all aspects of medical treatment for the first few days in order to establish a good working relationship with the patient and family. There may be both significant anxiety and pain, and the pain is not overwhelming. When the pain subsides, moderate anxiety usually also subsides, and the patient speaks of fears and worries. Emotions and confidence have an impact on all symptoms, however, some patients express negativity through somatic symptoms and shut themselves off from the great pain of relapse, and in fact, are common to patients with unresolved fears, unexpressed anger, and emotional conflicts. Functional abdominal pain (irritable bowel syndrome) may be a lifelong expression of negative emotions by the patient. There is no doubt that it proves impossible to change long-established behavioral patterns. 4. Suffering and pain at the same time Pain and suffering are not exactly the same; therefore, suffering must be distinguished from pain and other symptoms that may be associated with it. Patients can tolerate severe pain without thinking about the pain they themselves are going to suffer if they know that the pain has a definite cause and that the pain can be dealt with. The pain will be relatively short-lived.
