Often people come to see me because of back pain, but many tests are normal, and no other symptoms of kidney disease can be seen, such as swelling, hematuria, anemia, etc. This phenomenon is most obvious in the alternating seasons of cold and warm. For these people to be alert to other types of diseases, back pain is not necessarily kidney disease, lumbar disc herniation is also a very common disease. About 15-20% of manual laborers in China suffer from this disease, which mostly occurs in people aged 25-50, accounting for more than 75% of the total number of cases, and this kind of disease may be a little strange to the general population. We recommend a popular article on lumbar disc herniation, which will help us improve our understanding of the symptoms of low back pain, as well as our knowledge of prevention and protection against herniated discs. Some of the content may be a bit on the specialized side, but the illustrations in the article show very graphically how herniated disc lesions occur, the characteristics of low back pain symptoms, and how to exercise to prevent or mitigate this type of disease and the damage it brings.
