What is pain medicine? Pain medicine is an emerging discipline whose main task is to treat painful diseases that are not suitable for surgical treatment and the effect of drug treatment is not satisfactory, using some unconventional treatment means to achieve the purpose of treating the disease. Pain research and treatment has entered a specialized stage of development. Pain often coexists with other diseases or can appear alone, and requires a professional attitude to pain problems and professional means to manage them. How pain occurs Pain often occurs in daily life and work due to trauma, and can also occur after exposure to cold, humidity, overexertion and long-term inappropriate work positions. In addition, pain can be caused by inflammation or tumors in various systems and organs of the body. From the course of the disease, pain can be divided into acute pain and chronic pain, and from the part of the body, it can be divided into headache, neck and shoulder pain, chest and abdominal pain, lumbar and leg pain, etc. From the source of pain, it can be divided into soft tissue pain, joint pain, neuralgia, etc. Since the causes of pain and pain itself are very complex, it takes a certain period of time for a specialist to distinguish the categories and make a relatively clear diagnosis, and then to prescribe the right medicine. Pain can cause mental tension, depression or fear, and has a negative impact on all organs and systems of the body. In severe cases, it can be life-threatening and must be taken seriously. In the pain department, there are different answers for general and specific pain. Acute pain is divided into two categories: inflammatory pain and traumatic pain, and inflammatory pain is divided into infectious (such as appendicitis pain and hand and toe infection pain) and non-infectious (such as strain pain and gout); infectious pain must be treated with antibacterial agents, while non-infectious pain can be treated with painkillers. What about chronic pain? The most common chronic pains are rheumatic and rheumatoid pain, headache, shoulder pain and lumbar pain, etc.; the causes are complex and sometimes unknown, so general pain medication can be used, but it is better to go to the pain department to identify the causes and then prescribe the right medication, especially when the pain persists non-stop or gradually increases. How to deal with cancer pain At present, the common clinical three-step treatment can effectively control 80-90% of the cancer pain, but there are still 10-20% of patients who cannot get satisfactory pain relief, because the pain of these patients is so severe that it is difficult for the specialist to control, and the patients and their families suffer for a long time. At present, we can use standardized oral medication for pain relief; indwelling catheters to relieve pain at regular intervals; transvenous catheters; and blocked or destroyed nerves to achieve medium- and long-term pain relief. The use of comprehensive pain management methods can make cancer pain patients achieve the goal of basic pain-free. Intractable pain is most common in trigeminal neuralgia, herpes zoster pain and herniated disc pain, etc. The pain is so severe that it is unbearable for the patient, and when it is serious, the patient is restless.
