Low back and leg pain has been a major problem for many people. It has been reported that more than 80% of the population have had low back and leg pain many times in their lives, especially the elderly, who have a higher incidence. Some of them manifest as low back pain, some as leg pain, and some have both low back pain and leg pain at the same time; some others manifest as numbness, weakness and stiffness of the lower limbs. These symptoms are very common. Do you have the correct understanding? Have they been treated and dealt with correctly? First of all, you need to know the characteristics of your pain. 1. If your back pain is related to your activities and cannot be relieved or even aggravated by resting; or if your pain is obvious at night and affects your sleep; then you cannot ignore your condition because the above situations may indicate that you are suffering from primary or secondary tumors of the spine or serious degenerative spinal disorders, and you have to go to the regular medical institutions for treatment. 2. If your back pain does not affect your sleep, but only affects your sleep during your activities, and some other symptoms are numbness and stiffness in your lower limbs, do you treat and deal with them correctly? If your low back pain does not affect your sleep, but only occurs during or after activities, and is relieved after resting, you may suffer from lumbar spine muscle and soft tissue disorders (lumbar muscle strain, myofasciitis, lumbar spine 3rd transverse process syndrome, etc.), lumbar intervertebral disc degeneration, lumbar spine instability, lumbar spine slippage (isthmus fissure or degeneration), lumbar spine degenerative scoliosis, osteoporosis, and infectious diseases (spinal tuberculosis, spinal osteomyelitis, etc.). Most of the degenerative lumbar spine diseases can be relieved by conservative treatment, only when the pain seriously affects your daily life, then you need to perform surgical treatment; for osteoporosis, spinal tuberculosis, lumbar spondylolisthesis, lumbar spinal instability need to go to the hospital for diagnosis and make clear, to formulate the corresponding internal medicine or surgical treatment program; 3, if your back pain, the manifestation of the changes in the weather related to the wet weather can lead to pain Wet weather can cause pain, heavy symptoms in the morning, symptoms are relieved after activities, heavy symptoms in the morning, light symptoms in the afternoon. You may be suffering from rheumatologic and immunologic disorders, including compulsory spondylitis (usually young or middle-aged male patients), seronegative spondyloarthropathies, and so on. Such patients need to go to the rheumatology and immunology department for further consultation and treatment; 4. If your low back pain is combined with abdominal and chest pain, you may need to go to the internal medicine department for detailed examination. You may need to go to the internal medicine department to check in detail whether you suffer from chronic gastrointestinal diseases, heart and kidney diseases (coronary heart disease, nephritis, urinary stones, etc.), liver and gallbladder diseases, if you are a woman, you also need to exclude gynecological diseases, etc., do not take this kind of disease lightly. For only leg pain, no back pain patients, what are the possible aspects of the problem? 1, pain in the inner or outer thigh: may be discogenic pain, or high disc herniation; or hip osteoarthritis, etc.; 2, pain around the knee: may be intra-articular lesions in the knee joint (meniscus injury, osteoarthritis of the knee, rheumatoid arthritis), hip joint lesions, or lumbar intervertebral disc degeneration, etc.; 3, pain below the knee: most likely lumbar intervertebral disc herniation, or spinal stenosis, but also It may be meniscus injury. From the characteristics of pain, to determine the type of your disease 1, if the pain manifestation and weather changes related to the cold weather or rainy weather induced pain aggravation; have morning pain, a little activity relief, more activities and induced pain aggravation (that is, the so-called “old cold legs”), that is, the patient can be based on the pattern of the emergence of pain in the lower limbs to predict the weather changes. Weather changes. It is most likely to be osteoarthritis, which often occurs in the northern region; 2. If the pain manifestation is related to the weather changes, and the pain is aggravated by the humid weather, which has nothing to do with the hot and cold weather (the so-called “old wet leg”); and there is pain in the morning, which will be relieved after half an hour or more of activity, and the symptoms are heavy in the morning and light in the afternoon, then it is most likely to be rheumatoid osteoarthritis. It is most likely to be rheumatic osteoarthritis, or rheumatoid immune disorders, often occurring in the southern region; 3, if the leg pain is related to walking, walking for a period of time or distance after the leg pain, rest for 5 to 20 minutes after the relief of pain relief can continue to walk, and then the pain reoccurs (the so-called intermittent claudication); it is most likely to be lumbar spinal stenosis, osteoarthritis, vascular disease in the lower limbs. Self-identification tips, if cycling does not appear lower limb pain symptoms, but walking with the above symptoms, you may be lumbar spinal stenosis, rather than lower limb vascular disease. In addition, you need to clearly remind the problem is that you need to distinguish your lower extremity symptoms are pain, numbness, or lower extremity weakness, stiffness, sinking, or plantar sensation, which are fundamentally different, if it is the first type, then it is the type of the above mentioned, if your symptoms belong to the latter, then you may be suffering from not lumbar and leg disorders, but cervical spine, thoracic spine, craniocerebral, or neurological disorders. If your symptoms fall into the latter category, then you may not be suffering from a cervical, thoracic, cranial, or neurological disorder. Therefore, you need to make an initial decision on which specialty you need to consult based on the characteristics of your symptoms.
