Lumbogenic 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, skeletal artery, the digestive tract below the left curvature 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 involving 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, and it is more common in women with poor working position, such as standing, bending, weight bearing and other occupations. It is often misdiagnosed as “gastrointestinal spasm”, “gastrointestinal dysfunction”, “biliary ascariasis”, “biliary spasm or stone, ureteral spasm or stone ” etc. If it appears on the right side it is also easily misdiagnosed as appendicitis, and in some cases, surgery has even been performed but the abdominal pain still cannot be relieved. Pathogenesis: ① Visceral sensory nerve anatomy abdominal nerve distribution has spinal nerve and visceral sensory nerve, spinal nerve is distributed in the abdominal wall and the mural layer of peritoneum from T6-L1 spinal cord segment, visceral sensory nerve is distributed in the intra-abdominal organs and visceral layer of peritoneum, there is inductive connection between visceral nerve and spinal nerve. 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, 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 related to the plant nerve disorder associated with strain lesions of the soft tissues of the lumbar region. The anterior lumbar dorsal fascia is attached to the tip of the L1-4 transverse process. When aseptic inflammation occurs at this attachment, it can cause low back pain. Some cases are complicated by rib arch pain, belt-like tightness in the upper abdomen, abdominal discomfort, bloating, abdominal pain, belching, belching acid, eructation, poor appetite, indigestion, habitual constipation or chronic diarrhea (often diagnosed as allergic colitis). In cases of bilateral L1-2 transverse process pain, it may radiate upward and converge at the T11 or T12 spinous process, forming spinous pain with pressure points. If the examiner presses the L2 transverse process tips on both sides with both thumbs, the pain can be induced; then press the T11 or T12 spinous process, this spinous process pressure pain point will disappear completely; but when the pressure on the L2 transverse process tips on both sides is stopped, this spinous process pain will reappear again, indicating a causal relationship between the two. In some cases with complicated abdominal pain, the lumbar pain is often severe and the abdominal pain is mild; in some cases, the abdominal pain is severe and the lumbar pain is not prominent, often complaining of abdominal pain only, but the presence of a sensitive pressure point in the lumbar region is only clear during examination. These cases often lead to intestinal spasm and formation of abdominal masses due to pain, and are easily misdiagnosed as abdominal disorders or abdominal tumors, etc. L1-3 deep lumbar strain pain may cause rib arch pain, belt-like tightness in the upper abdomen, abdominal discomfort, bloating, abdominal pain, belching, belching acid, eructation, poor appetite, dyspepsia, habitual constipation, chronic diarrhea and other symptoms. Generally, the sites where the deep lumbar muscles of L1 to S2 are located and attached are the preferred sites for soft tissue strain lesions, which are more common clinically than the upper and lower sites; however, there are a few cases of deep lumbar muscle strain in L1 to 3 or the lower sacral segment, and the symptoms of L4 to S2 are more prominent. In cases of severe strain on the deep lumbar muscles of L1-3, even if a stereotyped lumbar or lumbar hip soft tissue release is performed and the entire deep lumbar muscles of L1-S4 are freed, the symptoms do not disappear because of the presence of secondary aseptic inflammation in the muscle belly there. There are many cases of residual pain that are misdiagnosed as incomplete soft tissue release of the transverse process of the lumbar region or the lower edge of the 12th rib. However, the residual pain symptom can be completely relieved by transverse lumbar dissection with a needle at this location. The deep lumbar muscle strain pain in L1 to S2 can be radiated forward and cause lower abdominal discomfort, lower abdominal pain, pain at the pubic bone attachment of the internal femoral retractor muscle group, male and female sexual function decreases or disappears, and female menstrual disorders and menstrual disorders. In the case of deep lumbar muscle strain in the lower sacral region, the pain may also radiate forward, causing symptoms such as anal or perineal discomfort, tingling, numbness, paresthesia, or spasm of the soft tissue between the two. Diagnostic points: (1) vague pain around the umbilicus or lower abdomen with less fixed pain points, sometimes with pressure pain but no 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 ruled out by physical examination and laboratory tests; (4) abdominal pain disappears or is significantly relieved after lumbar sympathetic block. Treatment: With a variety of comprehensive treatments such as lumbar acupuncture, physiotherapy, massage, compresses and oral medications, abdominal pain can be relieved or eliminated as long as the lumbar disorders are properly treated. Nerve block methods can also be used: continuous epidural block, posterior spinal nerve block, intercostal nerve block, intervertebral foramen block, lumbar 3 transverse process block, can receive immediate results. Part of the pathogenesis is due to a change in the anatomical relationship of the thoracolumbar spine with a small displacement, and manipulation for this cause is very effective.
