Sciatica is a term that describes symptoms of pain, numbness, and/or weakness that radiate along the sciatic nerve from the lower back to the buttocks and leg. The medical term for sciatica is lumbar radiculopathy.

　　「坐骨神經痛」這個術語用於描述從腰部向臀部和腿部沿坐骨神經走行區域的疼痛、 麻木、無力癥狀。「坐骨神經痛」的醫學名稱是腰椎神經根病。

The vast majority of sciatica symptoms result from lower back disorders between the L4 and S1 levels that put pressure on or cause irritation to a lumbar nerve root.

　　「坐骨神經痛」最常見的原因是腰4-骶1節段的腰椎疾患導致腰神經根受壓或刺激。

Most commonly, sciatica is caused by a disc problem, such as a herniated disc that is pressing against a nerve root.

　　通常，坐骨神經痛由椎間盤病變引起，例如椎間盤疝出壓迫了神經根。

It can also occur when a disc degenerates, which releases inflammatory proteins that irritate the adjacent nerve. There are many additional causes of sciatica.

　　椎間盤退變會釋放炎性蛋白，刺激相鄰神經，也可引起坐骨神經痛。坐骨神經痛還有許多其他的原因。

Sciatica symptoms are typically felt on only one side of the body. They may include a combination of leg and foot pain, weakness, tingling or numbness.

　　坐骨神經痛典型的感覺在身體的一側，包括腿和足的疼痛、無力、針刺感以及麻木。

Sciatica pain is often described as searing or sharp, as opposed to achy or throbbing.

　　坐骨神經痛常被描述成撕裂樣或尖銳的痛，而不是鈍痛或跳痛。

Depending on where the sciatic nerve roots are compressed, symptoms may be felt in different areas of the leg and into the foot.

　　根據坐骨神經受壓部位的不同，癥狀可出現於腿或足不同的位置。

It is important to remember that sciatica is a symptom of an underlying condition, not a diagnosis in itself.

　　重要的是，要記住坐骨神經痛是某種疾病的癥狀，本身不是診斷。
