In this article, experts will help us to introduce the symptoms of sciatica caused by intervertebral disc herniation.

Does intervertebral disc protrusion sciatica symptom?

The sciatic nerve is composed of the 4th and 5th lumbar nerves and the 1st, 2nd and 3rd sacral nerves. From the intervertebral foramen out of the spinal canal, it runs in the back of the pelvic cavity, in the lower part of the piriformis out of the hip, along the back of the thigh, the posterolateral side of the leg and the dorsolateral side of the foot. Sciatica usually refers to radiation pain along the sciatic nerve due to stimulation and compression for some reason. The main manifestations were paroxysmal or persistent channeling pain, especially at night. The pain parts mostly radiated from the buttocks to the back of thighs, the posterolateral side of legs and the lateral side of dorsum of feet. When encountering cough, sneezing and other actions that are easy to increase abdominal pressure, the pain will be aggravated. The pain could be alleviated by bending the knee and hip or lying on the side of the healthy side. The straight leg raising test was positive. Sciatica is only a clinical symptom, not an independent disease.

There are many causes of sciatica, including primary and secondary. The primary pain caused by inflammation of sciatic nerve is mostly unilateral, which can often occur simultaneously with MYOFIBROSITIS. The secondary lesions are adjacent tissue lesions of sciatic nerve, which produce pain caused by mechanical stimulation, compression or adhesion, such as lumbar disc herniation, lumbar spinal stenosis, ligamentum flavum hypertrophy, spondylolisthesis, lumbosacral or lumbosacral degeneration of lumbar spine, spondylolysis, lumbar tuberculosis, cauda equina neuroma, piriformis syndrome The stimulation of buttock injection of drugs can cause sciatica.

According to the site of sciatic nerve stimulation or compression, it can be divided into root sciatica and dry sciatica. Root sciatica, the affected parts in the root canal or spinal canal, patients often feel lumbosacral and leg pain, there are obvious tenderness points beside the lumbar spinous process, and along the sciatic nerve to lower limbs radiation, cough, sneezing and other actions to increase abdominal pressure can make the pain worse, can produce corresponding sensory disorders and reflex changes. Cerebrospinal fluid examination showed abnormal changes. Dry sciatica, involving the site outside the intervertebral foramen, pelvic outlet is the most common. Patients often feel radiation pain along a certain segment of the sciatic nerve. There are tenderness points below the buttocks along the direction of the sciatic nerve. There is no obvious tenderness near the spinous process. The pain is not obvious when coughing, sneezing and other actions increase abdominal pressure. There is no abnormal change in cerebrospinal fluid examination.
