Herniated lumbar disc foot fever is not necessarily a sign of improvement. Warm feet may be caused by environmental influences, or inflammatory factors mediated by inflammatory edema, congestion and other conditions, and lumbar disc herniation is not directly related to the lumbar disc herniation, so it is not necessarily a lumbar disc herniation improved performance. If the lumbar disc herniation improves significantly, symptoms such as low back pain and sciatic nerve pain will gradually decrease, and numbness in the legs can be gradually relieved when the compression reaction improves. Some patients with lumbar disc herniation may have symptoms such as lumbar tension and stiffness, and when the condition gradually improves, the related symptoms will gradually reduce or disappear. If you want to know whether the lumbar disc herniation has improved or not, you can’t recognize it simply based on the symptoms, and then you should go to the hospital for diagnosis and analysis through imaging tests, including lumbar CT, lumbar MRI, and so on.
