Patients with lumbar strain can choose from intervertebral foramen drug injection, painful point closure injection, and acupuncture point injection. If lumbar foramen drug injection is performed, the entry point should be found on the skin first, with the patient in prone position, and then the intersection of the 1 cm above the corner of the posterior edge of the iliac crest and the parallel line between the spinous process that you want to inject is found as the entry point. The needle is slowly inserted into the intervertebral foramen, and the drug is injected after backdrawing to make sure there is no blood or cerebrospinal fluid. Pay attention to aseptic operation as well as delicate operation to avoid damage to blood vessels and nerves. If closed injection of painful points is used, the painful points need to be selected for drug injection. If injection therapy is used, localized ayurvedic points can be selected, or meridian-tracking points can be selected according to the symptoms.
