Symptoms of sciatica:

First, sciatica often occurs in the lumbar 4 and lumbar 5, or between lumbar 5 and sacral 1 disc herniation.

Second, the primary symptom of sciatica is pain, which typically originates in the lower back and can radiate to the buttock, posterior thigh, the lateral side of the calf, and the lateral edge of the foot sole. Pain usually has a triggering factor, such as coughing, sneezing, defecation, etc., basically any activity that increases abdominal pressure can cause radiating pain of the sciatic nerve.

Third, the area innervated by the sciatic nerve may become hypersensitive, with some people feeling pain, others feeling heat, and still others feeling cold, until the later stages where it generally becomes numbness and dullness.

Fourth, there are limitations in movement of the lower back or limbs, with many patients reporting a feeling as if there’s a shortened tendon at the back of the thigh, restricting movement.

These are the primary symptoms of sciatica.
