It is a pathology that appears when the sciatic nerve, which originates in the lower spinal column (L4, L5, S1 and S2), is injured at some point along its course.The most common cause is intervertebral disc herniation.
It is characterised by low back pain which extends to the glutes, back of the leg and dorsum of the foot.
It is usually described as an intense stabbing pain that is aggravated by walking, sitting, coughing, defaecation and compression of the spinal point where the injury has occurred.
Diagnosis is made on the basis of the patient's complete medical history review and a physical examination. It is confirmed by imaging tests that reveal herniation of the intervertebral disc.
The priority of treatment is to relieve pain with analgesics and anti-inflammatory drugs, and complete rest is not necessary. Physiotherapy sessions may be beneficial. In some cases, surgical treatment will be necessary.
