Lumbar-derived abdominal pain is a chronic lesion caused by soft tissue strain in the low back. The course of the disease can last for months or even years. The preganglionic fibers of the lumbar sympathetic nerve mainly come from L2-3 nerve roots, while the postganglionic fibers mostly emanate from the anterior branches of the upper two pairs of nerves and join the spinal nerve via the gray traffic branch to accompany the vascular distribution in the lower limbs, and distribute via the dirty branches to the abdominal aorta, the skeletal artery, the digestive tract below the left flexure of the colon and the pelvic organs. Soft tissues such as lumbar vertebrae and small joints, paravertebral myofascia and other soft tissues cause local aseptic inflammatory changes due to foci remaining after trauma and strain, forming foci of irritation or referred to as provoked pain points, involving the spinal nerve roots before and after causing lumbar sympathetic nerve dysfunction, resulting in abdominal pain and involvement pain. The high incidence in women may be related to the physiological anatomical characteristics of women. The incidence of abdominal pain is high in women, which may be related to the physiological anatomical characteristics of women. Among them, it is more common in professional women with poor working position, such as standing, bending, weight-bearing, etc., and the stressful mental factors have some influence on the development of certain disease processes. The spinal nerves are distributed in the abdominal wall and the peritoneal wall from the T6-L1 spinal cord segment, and the visceral sensory nerves are distributed in the intra-abdominal organs and the visceral peritoneum, and there is an inductive connection between the visceral nerves and the spinal nerves. Any lesion that can stimulate or compress the visceral sensory nerves in the abdominal cavity can produce different degrees of abdominal pain. The abdominal wall and lumbar soft tissues anatomically are mostly originated from the lumbar soft tissues (internal and external oblique abdominal muscles and transverse abdominal muscles from the lumbodorsal fascia and its starting point L1 transverse process), so the lumbar soft tissue lesions can often involve the abdominal wall tissues and cause abdominal pain. In addition, the production of abdominal pain is sometimes associated with plant nerve disorders associated with strain lesions of the soft tissues of the lumbar region. Diagnostic points: (1) vague pain around the umbilicus or lower abdomen with less fixed pain points, sometimes with pressure pain but without rebound pain; (2) single or multiple pressure pain points in the transverse process of the lumbar vertebrae at the lateral edge of the sacrospinous muscle: (3) organic lesions in the abdominal cavity and pelvic organs are excluded by physical examination and laboratory tests; (4) abdominal pain disappears or is significantly relieved after lumbar sympathetic nerve block. Treatment: With the application of lumbar warm acupuncture, physiotherapy, massage, compresses and other comprehensive treatments, abdominal pain can be mostly relieved or eliminated as long as the lumbar disorders are properly treated. Nerve block methods can be used: continuous epidural block, posterior spinal nerve block, intercostal nerve block, intervertebral foramen block, lumbar 3 transverse process block. ①Local anesthetics can effectively block painful stimulation and muscle and soft tissue spasm, improve local blood circulation, anti-inflammatory and anti-swelling. ②Corticosteroids inhibit fibroblast proliferation and granulation tissue formation, reduce inflammation-induced scarring and adhesions, enable local sterile inflammation to be eliminated as soon as possible, and prevent re-adhesion. ③Lumbar sympathetic nerve block for lumbar origin abdominal pain with rapid effect.
