1, pain is not a disease, can endure it. ”Pain” is the earliest and most subjective sensation experienced by every person in his or her life, and is the main signal of damage to human tissues and organs. It serves as a protective signal that makes people avoid danger or go to the doctor. For chronic pain that is still tolerable, many people do not take it seriously and tolerate it as long as they can. In fact, pain not only causes mental suffering, loss of labor force and quality of life, but also causes disorders in the function of various organs and systems, low immunity and various complications, which greatly shorten the life span of people. The World Health Organization has clearly put forward: “Acute pain is a symptom, chronic pain is a disease”. The Department of Pain is precisely the professional department to solve various chronic pain, chronic pain disease should be timely to the Department of Pain to seek medical attention. 2, no matter what method is used, stop the pain first. The “headache to cure the head, the foot to cure the foot” is the extreme wrong method. Therefore, the correct treatment of chronic pain is: on the basis of a clear cause, through the treatment of the cause, the removal of inflammatory metabolites, effectively improve local blood circulation disorders, interrupt the vicious cycle of pain, to achieve long-term perfect analgesic purposes. If the pain is injected with dulcolax indiscriminately, the condition will be delayed because the pain is temporarily covered up, which will surely cause serious medical accidents, so the correct method of analgesia must be adopted. 3. Cancer patients can only rely on medicine and injection to relieve pain. For cancer pain patients, with the development of the disease, the traditional oral and injectable drug delivery methods may have disadvantages such as incomplete analgesia and large side effects. The latest pain interventional treatment-subarachnoid programmable morphine pump implantation-brings light to cancer pain and chronic intractable pain patients. The subarachnoid programmable morphine pump enables the release of very small amounts of morphine in the subarachnoid space at a uniform rate, and the amount of morphine release can be adjusted at any time by means of in vitro programming, which greatly improves the analgesic effect of morphine and reduces adverse effects. The biggest advantages of this method are significant and long-lasting efficacy, less patient pain and fewer adverse drug reactions. This technology has been widely carried out in Europe and America and other countries with convincing results, and many hospitals in China have also carried out this technology. With the continuous popularization of this technology, it will no longer be a dream for cancer pain patients to enjoy a comfortable and happy life. 4.Cervical spondylosis and lumbar spondylosis can only be operated when conservative treatment is ineffective. The vast majority of people are afraid of surgery because they are afraid that it will be traumatic and risky, and what if the pain is not cured, but worsened or paraplegic? This fear is understandable. In fact, there are many interventional procedures for pain management that do not require an incision. Under imaging guidance, a very fine puncture needle is used to reach the lesion and selectively block the nerve or dissolve the nucleus pulposus to treat spinal neuralgia or herniated discs in a physical or chemical manner, with an efficiency of more than 90%. Of course, not all spinal lesions can be used in this way, and some serious people should be operated. 5, after the wind back pain is only the wind and cold, my lumbar spine itself is not a problem. Inappropriate posture or cold is the triggering factor of low back pain, but often has its underlying disease – small joint disorders are the main cause of local nerve compression, producing inflammatory edema. X-rays of such patients are often normal, but do not indicate that there is no problem in the lumbar spine, because early inflammation of the compressed nerve does not always show up on imaging. Medication, physical therapy, and nerve blocks can relieve pain and eliminate inflammatory edema. Such patients should usually pay attention to the protection of the spine: avoid prolonged sitting, so as not to increase the burden on the lumbar spine; appropriate calcium supplementation, the choice of easily absorbed calcium supplement products; pay attention to warmth. 6, morphine, dulcolax is the highest stage of treatment of all pain. In fact, it is not. Central pain caused after head spinal cord injury, local complex neuralgia caused by peripheral neuropathy, phantom limb pain, etc. The effect of opioid painkillers is not ideal: the negative effect brought by high dose morphine is much greater than its positive effect. The mechanisms of pain are complex and not all of them can be explained by opioid receptor mechanisms, and for these pains must be treated from the central stage. At present, the most advanced international deep brain electrical stimulation and spinal cord electrical stimulation have been an effective treatment for these diseases with many successful cases. 7, the original disease is cured how still pain. Some people are cured of herpes zoster, but months or years later the original herpes area occurred stubborn severe pain, especially the elderly and frail or have chronic diseases are more likely to occur, this is called postherpetic neuralgia, is a kind of sequelae pain, is due to nerve cell degeneration damage. To avoid this, regular antiviral and timely analgesic treatment must be administered during the acute outbreak phase to avoid permanent and irreversible damage to the nerves due to virus latent at the nerve roots. In addition, immunity must be enhanced and comorbidities controlled. 8. The surgery was successful and the imaging was normal, how come the pain is still there. It is true that many patients after spine surgery or cranial surgery have this narrative. Modern medicine believes that health is not only about normal body morphology, but also about normal function, and this concept must be established. Pain medicine is the science that addresses function. To give a simple example, if an elderly person has degenerative changes in the spine that cause nerve compression and produce inflammatory edema and pain, if the nerves can be nourished or blocked in the easiest and most effective way, the pain will naturally be relieved. If the bones are revised in a major way, new pain may arise before the old one is resolved, which is undesirable.
