Some patients who develop a herniated lumbar disc may have symptoms of pain in the caudal vertebrae. The reason why such patients have such performance may be due to the following mechanisms: First, when the patient has an attack of lumbar disc herniation, it may be due to the herniated nucleus pulposus compressing the nerve roots, followed by radioactive pain in the lumbar and sacrococcygeal regions, at which time the patient may mistakenly think that the problem is in the caudal spine. Secondly, it may also be due to other diseases when the patient has an attack of lumbar disc herniation, for example, some patients may first have an attack of lumbar disc herniation, and during the treatment of such diseases, it is necessary to maintain a supine position for a long time. This may cause pressure sores or aseptic inflammation in the sacrococcygeal area, and the patient may feel pain in the caudal region. For patients with these symptoms, prompt treatment of the primary lesion of the herniated lumbar disc is required. Pain in the caudal spine can be treated with topical medication, such as topical creams applied here.
