Numbness is a symptom of irritation, injury, inflammation, and compression of the corresponding nerve tissue caused by a variety of factors, which in turn causes a decrease or loss of the body’s ability to perceive. The hip is close to the lumbar region, and when the nerves near the hip or lumbar spine, especially the sciatic nerve, have the abnormalities mentioned above, the symptoms of numbness can occur on one side of the hip. Numbness on one side of the hip can be considered for more diseases, commonly including long-term pressure on the hip muscles, lumbar disc herniation, and may also be caused by local inflammation, neuroinflammation and rare lumbar spine tuberculosis and tumors: 1. Long-term pressure on the hip muscles: if there is a lack of activities on weekdays and poor sitting posture for a long time may cause numbness on one side of the hip muscles after nerve pressure; 2. Lumbar disc herniation: due to nucleus pulposus protrusion Stimulation or compression of the nerve root, cauda equina nerve and indirect stimulation of the sciatic nerve, sciatica, lumbago and lower limbs including hip numbness and other symptoms. In addition, long-term bending may also stimulate the sciatic nerve and cause numbness on one side of the hip; 3, neuritis: when inflammation occurs in the hip, nearby parts of the lumbar spine or peripheral nerves, numbness on one side of the hip may also occur; 4, other: such as lumbar spine tuberculosis, tumors, etc., often accompanied by severe symptoms of lumbago, when the lower lumbar spine tuberculosis with tuberculosis abscess, or tumor growth and other protrusions into the spinal canal, the spinal cord or nerve roots can be When the lower lumbar spine tuberculosis is complicated by tuberculosis abscess, or when the tumor grows into the spinal canal, the spinal cord or nerve roots may be stimulated and sciatica may appear, which may cause numbness in one side of the hip.
