Pain is not the “patent” of the elderly, many young white-collar workers are also cervical and lumbar pain and other office occupational diseases. However, many people do not know which section to look at when the body pain, such as many women from adolescence onwards with intractable migraine, to the menopause is still in pain. Gynecology and neurology have been seen all over, and have not completely solved the problem. When many people experience pain, they will buy some painkillers on their own to relieve the pain for a while. In the use of medication to relieve pain, people also have a lot of misunderstandings. Misconception 1: pain is intense painkillers Many people always stay away from painkillers, fear that painkillers will be resistant and even addictive and many other side effects, that will be fine if you stay up for a while. In fact, if the pain is not effectively resolved, the constant pain often also causes a series of psychological changes in the patient, such as despair, restlessness, irritability, resulting in increased sensitivity to pain and further deterioration of the patient’s condition. Suggestion: Give medication on time and as needed. Professor Wong emphasized that timely use of painkillers is safer and more effective, and requires the lowest strength and dose of painkillers. In fact, the dose of morphine used clinically for pain relief has a very low likelihood of creating psychological dependence (addiction). Long-term use of opioid painkillers in patients with cancer pain may require a gradual increase in dosage, which can also be successfully withdrawn when the pain subsides or when necessary. Addiction to non-injectable medications is even more unlikely. There is now a fentanyl transdermal patch called Duregix, which mixes a strong opioid with a gel-like substance and applies it to the skin, releasing it slowly at a constant rate, which is much safer. Myth 2: Dulcolax is the best painkiller Dulcolax, also known as pethidine in medicine, has a long history of application in China and is the most familiar analgesic to doctors and the public. Many patients and their families believe that Dulcolax is the “best” analgesic, so when the pain is severe, patients or their families often request the use of this drug. However, when the drug is discontinued, patients often experience mental depression, general discomfort, tears and tears, vomiting, diarrhea, insomnia, and in severe cases, weakness. As a matter of fact, Dulcolax’s pain relief strength is only 1/10 of that of morphine, and its intramuscular injection has potential neurotoxicity and nephrotoxicity and other side effects. If used continuously for 1-2 weeks, it can produce drug dependence, and some people will gradually become addicted to it. Suggestion: When Dulcolax is used in the treatment of cancer pain, it has the disadvantages of short duration of action, unstable blood concentration and rapid drug resistance. The World Health Organization does not recommend injecting Dulcolax to patients with chronic pain, and the relevant documents of the State Ministry of Health stipulate that Dulcolax can only be used for short-term acute pain, and Dulcolax is not recommended for patients with cancer pain. Tips: Chronic pain is a disease, can not buy painkillers at random on the matter. Chronic pain needs to be diagnosed and treated by a specialist. Therefore, no matter which part, as long as the pain is more than a month, you should go to the hospital. If the relevant departments have not solved the problem, you should look for a doctor in the pain department.
