Back and leg pain is a common symptom in the elderly, and many people think it is related to the strain they had when they were young. Whenever they have pain, they just put up with it and it passes. Or you can go to a Chinese medicine clinic and get some Chinese herbs, or get some pain relief cream. Physical therapy and massage are also popular “all-purpose” treatments, and many older people will choose this treatment. These are all things to try. If it is recurring or getting worse, you should pay attention to it. You should at least see a specialist to find out what the problem is. Especially those who do not get better after orthopedic or other specialist treatment. In recent years, our department has admitted dozens of patients with malignant tumor bone metastasis with back pain and leg pain as the first manifestation. Some of them are back pain, and they went to the hospital for some X-rays, saying that it is lumbar disc herniation, or some osteophytes, or even osteoporosis. Because all these diseases can lead to back and leg pain and are common causes, they are the first to be “favored” by doctors and older people. It should be noted that although these diseases are common among the elderly, they are also a high risk group for tumors. No one wants to get tumor, but not everyone can be free of tumor. If the tumor is found early, there is still a way to treat it, but if it is at an advanced stage, it is a serious problem, leading to paraplegia is common. According to the survey of our patients, many of them went to some hospitals and did have their films taken, but they were not diagnosed. Why? I think there are several reasons: first, the patient has a history of disc herniation or osteoporosis, so the doctor can easily diagnose retrospectively; second, the patient has symptoms and X-ray changes, so the doctor can easily diagnose; third, there are changes in X-ray examination, but the physician does not combine with the clinic and does not see them (no experience in X-ray diagnosis of tumor bone metastasis); fourth, the specialist physician does not have the concept of tumor, and his attention is mainly focused on the specialist disease. Fourthly, the specialist physicians do not have the concept of tumor, and their attention is mainly focused on the specialist disease. Therefore, if the back pain and leg pain cannot be relieved for a long time, especially if it is aggravated in elderly people, it should be given enough attention. Excluding tumor is also an important issue for you to consider. Suggestions are as follows: 1. When X-ray film is available, you can go to a specialist hospital, or oncology department for consultation; 2. Perform CT or MRI scan to check the site against X-ray to get more evidence; 3. Or perform whole body bone scan examination, which can detect the problem in time and help to diagnose.
