Sciatica, as this eMedTV Web page explains, is a serious condition that can cause numbness and some loss of motor control over the leg. This page also describes the symptoms, causes, and factors that can affect treatment.
In about 90 percent of cases, sciatica causes are linked to a herniated disc. This portion of the eMedTV library describes this and other possible causes, such as spinal stenosis, fracture, infection, or degeneration of the sciatic nerve.
The severity of sciatica symptoms depend on how much of the sciatic nerve is compressed. This eMedTV article highlights both common and severe symptoms, ranging from burning low back pain to loss of muscle control.
This section of the eMedTV Web site provides a detailed look at options for sciatica pain relief, which include hot and cold compresses, pain-relieving medications, minimal bed rest, physical therapy, and surgery.
