The pain usually radiates from the waist to one side of the buttocks and thighs, the popliteal fossa, the lateral side of the lower leg and the foot, presenting as burning or knife cutting pain. The pain can be aggravated when coughing and exerting, especially at night. In order to avoid nerve traction and compression, special pain reducing postures are often adopted, such as lying to the healthy side when sleeping, flexing the hip and knee, exerting on the healthy side when standing, causing scoliosis for a long time, bending to the healthy side more often, and leaning to the healthy side when sitting into the hip, so as to reduce the compression of nerve roots. Traction of sciatic nerve can induce pain or aggravate pain, such as positive Kernig sign and positive straight leg raising test (Lasegue sign).

Pain often radiates from the hip to the back of the thigh, the posterolateral side of the leg and the lateral side of the foot. The pain aggravated when walking, moving and drawing sciatic nerve. The tenderness point was below the gluteal point, Lasegue sign was positive, while Kernig sign was negative.
