Low back pain is said to be a “popular disease”. According to foreign data, about 70% to 80% of people in developed countries suffer from it. There are many causes and diseases that cause low back pain, and the duration of low back pain can be as little as a few days or as long as several decades. There are many methods of treatment, and medication is one of the common ones. The drugs commonly used in hospitals are antipyretic and analgesic drugs and some proprietary Chinese medicines, which are effective and have a certain effect on relieving most of the symptoms of low back pain, while they are convenient and easy to obtain, simple to take and quite cheap. However, if used improperly, they not only affect the therapeutic effect, but also may cause a variety of complications. It is well known to prescribe the right medicine for the right symptoms. When low back pain appears, a clear diagnosis is needed before medication is administered. Because low back pain is a non-specific symptom, its manifestation is similar but caused by different reasons, and the treatment and medication also differ. In most cases, medication only treats the symptoms but not the root cause, and cannot solve the problem at the root. For example, severe lumbar disc herniation, lumbar spinal stenosis, vertebral body slippage and tumors require surgery, and medication alone is not effective. Mild lumbar disc herniation and lumbar strain are best treated with methods such as massage and physiotherapy, along with medication. The decision of which kind of back pain the patient belongs to and what kind of treatment method is suitable should be made after examination by a specialist. Most of the drugs for low back pain have obvious stimulating effects on the gastrointestinal tract, which can cause stomach discomfort, nausea, vomiting, loss of appetite, and in serious cases, can damage the gastric mucosa and cause ulcers and even perforation. There are also drugs that can cause damage to the liver and kidneys as well as lowered white blood cells and allergic reactions. Those who originally had gastric ulcer, gastroenteritis, and abnormal liver function may also aggravate the condition. For this reason, patients with such conditions should take the initiative to tell the doctor truthfully, otherwise, in case the doctor neglects to ask about it, the above-mentioned problems may arise. Some patients have a significant reaction to a certain drug, but may tolerate several others. If you are unwell during the medication period, stop the medication first and then go to the hospital to consult a doctor or have the necessary laboratory tests done to decide whether to stop the medication, reduce the dosage or switch to other medications. Chinese medicine also has side effects Many people believe that Chinese medicine has no side effects. It is a misconception that it is safe, but there is no harm in taking it. It is true that traditional Chinese medicine is concerned with the theory and method of prescription and the combination of drugs, often using several drugs to inhibit and moderate the side effects or toxicity of other drugs, but not without side effects, such as back pain patients commonly used to activate the dan contains cinnabar, that is, mercury compounds. Mercury is a harmful substance that can accumulate in the body and cause toxic symptoms such as proteinuria and urethritis when taken for a long time. Some Chinese medicines for back and leg pain contain strychnine, which can easily lead to liver and kidney damage when taken by elderly patients with back and leg pain. Various medicinal wines are also commonly used by patients with low back pain. Some patients with poor liver function or poor tolerance to alcohol can suffer from chronic alcoholism and liver damage when taken for a long time. Therefore, whether it is western medicine, Chinese medicine or proprietary Chinese medicine, it is important to prevent side effects. The advantages of topical medication are obvious in comparison. By applying ointment paste or medicine to the painful area, the medicine can reach the deep tissue through the skin. Because it mainly works locally and does not interfere with the physiological activities of the whole body, it has few side effects and is easy and convenient to use. However, repeatedly applying, applying and rubbing for too long may cause dermatitis. In addition, for especially obese patients, it may be difficult for the medicine to penetrate due to the thick subcutaneous fat, resulting in poor results. Some patients with chronic back pain, treated with drugs for too long, are prone to cumulative side effects. Very few patients even develop drug dependence, taking larger and larger doses of drugs, and the side effects become more and more obvious, but they still have to take them, otherwise they feel uncomfortable. In view of this, patients with long duration of back pain should try not to take or take less painkillers from the beginning of treatment, and try to use local medication or massage, physiotherapy, acupuncture and other treatment measures. Pay attention to the dosage of medicine really must take medicine, can be replaced by other varieties of similar drugs in a period of time. It is also important to note that similar drugs should not be combined in the course of administration. Instead, the side effects may instead be more pronounced. The higher the dose of a drug alone, the better the efficacy. Therefore, do not increase the medication or the dose at will. Back pain in pregnant women is generally caused by the physiological changes of pregnancy and increased weight bearing of the lumbar spine, which is mostly mild and disappears naturally after delivery. Pregnant women generally should not take painkillers because many drugs may endanger the fetus and damage the pregnant woman, so they should not use drugs at will. Elderly people have reduced liver and kidney function, often accompanied by other diseases, and the metabolism of drugs is slow, so they should be more cautious when using drugs, and the dose should be small.
