In addition to the inflammatory irritation of the nerve, a herniated lumbar disc often causes a certain degree of extrusion and adhesion to the nerve root, etc., causing recurrent nerve root symptoms that do not heal. The intervertebral foramen is the orifice through which the spinal nerve passes, and in addition to the spinal nerve, there are also the intervertebral foramen septum and ligaments, etc. These cause restrictions on the compressed nerve. When the disc is herniated, the direct pressure on the nerve root, together with the restrictions of the intervertebral foramen septum and ligaments, make the space for the nerve root to move narrow, and the sensitivity of the nerve increases, and obvious nerve symptoms, including pain and numbness, will appear after activity or exertion. After years of observation, we have used intervertebral foraminal nerve root acupuncture release to expand the space for nerve root activity, reduce nerve hypersensitivity, and promote nerve root repair, and have achieved significant results. It is particularly effective in patients with chronic recurrent disc herniation, and it is also very effective in patients with postoperative pain syndrome and residual symptoms after interventional treatment.
