The symptoms of lumbar disc herniation have certain characteristics, and we must pay attention to these danger signs. The main symptoms of lumbar disc herniation are: 1. Lumbar pain Most patients with lumbar disc herniation have a history of lumbar pain for weeks or months, or a history of recurrent lumbar pain episodes. Generally, the symptoms are relieved after rest, and the pain can be aggravated by coughing, sneezing or straining during bowel movement. 2.Lumbar movement disorder The lumbar movement is affected in all aspects, especially the posterior extension disorder is obvious. In a few patients, the symptoms of lumbar disc herniation are significantly limited in forward flexion. 3. Scoliosis Most patients have varying degrees of lumbar scoliosis. The direction of scoliosis can indicate the location of the herniation and the nerve root, which is also a lumbar disc herniation symptom. 4. Radiating pain in the lower extremity Radiating pain in the sciatic nerve region of one side of the lower extremity is the main lumbar disc herniation symptom, often appearing when the lumbar pain disappears or is reduced. The pain starts from the buttocks and gradually radiates to the back of the thigh, the outside of the calf, and some may develop to the outside of the dorsum of the foot, the heel or the palm of the foot, affecting standing and walking. If the herniation is in the center, the symptoms are in the cauda equina nerve. If the herniation is bilateral, the radiation may be bilateral or alternating, which are all symptoms of lumbar disc herniation. Symptoms of lumbar disc herniation in life must be timely medical attention to avoid serious consequences, and at the same time, in daily life, must maintain the correct posture, develop good habits and do a good job of prevention of lumbar disc herniation from many angles.
