Sciatica

Sciatica: Introduction

Sciatica is a common group of symptoms that occur when the sciatic nerve is compressed, injured, and/or inflamed. The sciatic nerve is the longest nerve in the body and branches out from the spinal cord in the lower back through both buttocks and legs. The sciatic nerve and its branches are responsible for movement and feeling in the legs and feet.

Compression, injury or inflammation of the sciatic nerve results in symptoms that typically include intense pain anywhere along the nerve path through the legs and feet. Weakness and numbness can also occur. Sciatica may also result in complications. For additional symptoms and complications, refer to symptoms of sciatica.

Sciatica frequently occurs due to a bulging or herniated disc in the spine, which can pinch the sciatic nerve. Sciatica can also occur due to trauma to the spine, osteoarthritis, degenerative disc disease, pregnancy, or rarely, a spinal tumor.

Sciatica is often diagnosed and treated by a spine specialist or a chiropractor. Making a diagnosis of sciatica begins with taking a thorough medical history, including symptoms. A physical and neurological examination that focuses on the back and lower extremities is also done and includes an assessment of range of motion of the back and legs. A neurological exam is performed to evaluate the muscles, nerves and nervous system and such functions as reflexes, sensation and pain, movement, balance, and coordination.

Diagnostic testing may include special tests that test the nerves and muscles. These include an electromyogram (EMG), which tests the nerve and electrical activity of muscles, and a nerve conduction velocity test, which identifies how fast nerves conduct electrical impulses. Medical testing may also include tests that can help determine any underlying medical disease or conditions that may be causing sciatica. These include imaging tests that create a picture of the spine, such as spinal X-ray, CT and/or MRI.

It is possible that a diagnosis of sciatica can be missed or delayed because symptoms may be mild or similar to symptoms of other diseases and conditions. For more information about diseases and disorders that can mimic sciatica, refer to misdiagnosis of sciatica.

Treatment for sciatica varies depending on the severity of symptoms, the presence of complications, a person's age and medical history, and the type of work and activities a person does. Treatment can reduce or eliminate symptoms and complications. Treatment options include chiropractic therapy, physical therapy, exercises, medication, alternative therapies, and possibly surgery.

Article Excerpts about Sciatica

Sciatica is a painful condition caused by pressure on the sciatic nerve, the main nerve that branches off the spinal cord and continues down into the thighs, legs, ankles, and feet. Sciatica is characterized by pain in the buttocks and can be caused by a number of factors. Exertion, obesity, and poor posture can all cause pressure on the sciatic nerve. One common cause of sciatica is a herniated disc (see Spine Basics in the Appendix). (Source: excerpt from Pain -- Hope Through Research: NINDS)
