What is sciatica?
Sciatica is a term used to describe the presence of symptoms affecting the low back and legs. Often originating in the spine, sciatica can have several different causes including disc herniation, disc disease, piriformis syndrome or spinal stenosis.
What are the symptoms?
Symptoms of sciatica can include pain the buttock (usually only on one side) which often increases with sitting. You may experience burning, tingling or searing pain in your leg. Weakness, numbness or difficulty moving the leg or foot may also be present.
Symptoms are caused by an irritation or compression of one or more of the nerve branches in the lower back that join to form the larger sciatic nerve. The sciatic nerve may also be compressed by muscles as it extends down the leg.
How is sciatica diagnosed?
To diagnose sciatica, your physician will review your health history and perform a physical examination. They may also recommend imaging such as x-ray or MRI to assist in diagnosis.
How is sciatica treated?
Most people find relief from their sciatica with non-surgical methods. These treatments include the use of pain medications, application of heat or ice, injections, exercise, physical therapy or other manual therapies.
In more severe cases where non-surgical methods do not bring relief, surgery may be considered to decompress the nerve.
When you have pain caused by a pinched nerve, it can be challenging to evaluate your treatment options. Although nonsurgical treatment is effective for 90 percent of spine pain, there are some specific conditions that are best treated by surgery.
Radiculopathy is a spinal nerve root condition caused by nerve compression, inflammation, or injury that can trigger back and leg pain. When this injury is located in the lower part of the spine, it is called lumbar radiculopathy. Spine surgeon Dr. Wills explains how lumbar radiculopathy is diagnosed.
Our nerves transmit information to our brains. Spine surgeon Dr. Nicholas Wills reviews the relationship between our nerves and our spinal cord, and explains how pressure can disrupt nerve function, causing arm or leg pain.
