Lumbar disc herniation is more painful after taking closed injection, which may be caused by nerve damage or adhesion of lumbar muscles, etc. Conservative or surgical treatment can be taken. 1. Conservative treatment: If the puncture is not standardized, it may lead to nerve injury and increase the pain in the lumbar region, or the adhesion of lumbar muscles caused by the injection may also increase the pain. You can take non-steroidal anti-inflammatory pain medication, such as ibuprofen extended-release tablets, to relieve pain symptoms, or local massage to promote local blood circulation, improve adhesion symptoms and relieve pain. 2. Surgery: If the pain cannot be relieved by conservative treatment, or if daily life is seriously affected, surgery can be performed to remove the protruding discs or loosen the adhesive muscles, so that the compression can be relieved or the adhesive muscles can be relaxed, and the pain symptoms can be relieved completely. The above medication should be administered under the guidance of a doctor, do not self-medicate, and if you experience more pain after taking a closed injection, it is recommended that you consult a doctor in a timely manner to find out the cause of the pain and carry out the treatment.
