Sciatica意思

"Sciatica" is a medical term that refers to pain that originates in the sciatic nerve, which is the longest and widest nerve in the body. The sciatic nerve runs from the lower back down the back of each leg. Sciatica is characterized by pain, tingling, numbness, or weakness that radiates along the path of the sciatic nerve, which can extend from the lower back down the leg and into the foot.

Sciatica is not a condition in itself but a symptom of a problem with the sciatic nerve. It is often caused by compression or irritation of the nerve, which can be due to a herniated disc, spinal stenosis, piriformis syndrome, or other conditions that put pressure on the nerve. The pain can be mild or severe and may be accompanied by other symptoms such as difficulty walking, muscle weakness, or difficulty controlling the leg muscles.

Treatment for sciatica can include rest, physical therapy, pain relievers, corticosteroid injections, and in some cases, surgery. It is important to seek medical attention if you experience symptoms of sciatica, as early treatment can help to prevent the condition from worsening.
