A lumbar disc herniation usually does not cause swelling, hardening, or enlargement of one side of the lower back or abdomen. Lumbar disc herniation usually involves the lumbar and sciatic nerves, thus causing low back pain and radiating pain in the lower limbs, often accompanied by numbness and weakness in the lower back. Some patients will often feel a loss of muscle strength in the lower limbs, but will not experience swelling, enlargement and hardening of one side of the waist and abdomen. The swelling, enlargement and hardness of the lower back and abdomen are usually related to constipation, indigestion, or lesions caused by fluid accumulation in the abdominal cavity, such as cirrhosis of the liver, venous reflux disorders and pelvic tumors, etc. These diseases have no actual relationship with lumbar disc herniation. Patients suffering from lumbar disc herniation should consult the Department of Spinal Medicine and be analyzed by lumbar spine CT and MRI. However, patients with lumbar and abdominal distension, enlargement and hardness should go to the general surgery department, and abdominal ultrasound and color ultrasound can be done if necessary.
