Sciatica

Sciatica is a condition that causes pain in the lower back that spreads down into the buttock, hip, and leg. Sometimes the leg pain can happen without any back pain. Sciatica happens when a spinal nerve is irritated or has pressure put on it as it comes out of the spinal canal in the lower back. This most often happens when a bulge or rupture of a nearby spinal disk presses on the nerve. Sciatica can also be caused by a narrowing of the spinal canal (spinal stenosis) or spasm of the muscle in the buttocks that the sciatic nerve passes through (piriformis muscle). Sciatica is also called lumbar radiculopathy.

Sciatica may begin after a sudden twisting or bending force, such as in a car accident. It can happen after a simple awkward movement. In either case, muscle spasm often also happens. Muscle spasm makes the pain worse.

A healthcare provider makes a diagnosis of sciatica from your symptoms and a physical exam. Unless you had an injury from a car accident or fall, you usually will not have X-rays taken at this time. This is because the nerves and disks in your back cannot be seen on an X-ray. If the provider sees signs of a compressed nerve, you will need an MRI scan.. Signs of a compressed nerve include loss of strength in a leg.

Most sciatica gets better with medicine, exercise and physical therapy. If your symptoms continue after medical treatment, you may need surgery or injections to your lower back, depending on how severe your symptoms are.

Home care

Follow these tips when caring for yourself at home:

• You may need to stay in bed the first few days. As soon as possible, begin sitting up or walking. This will help you avoid problems that come from staying in bed for long periods.
• When in bed, try to find a position that is comfortable. A firm mattress is best. Try lying flat on your back with pillows under your knees. You can also try lying on your side with your knees bent up toward your chest and a pillow between your knees.
• Avoid sitting for long periods. This puts more stress on your lower back than standing or walking.
• Use heat from a hot shower, hot bath, or heating pad to help ease pain. Massage can also help. You can also try using an ice pack.
• You can make your own ice pack by putting ice cubes in a plastic bag. Wrap the bag in a thin towel. Try both heat and cold to see which works best. Use the method that feels best for 20 minutes several times a day.
• You may use acetaminophen (Tylenol) or ibuprofen (Motrin) to ease pain, unless another pain medicine was prescribed. Note: If you have chronic liver or kidney disease, talk with your healthcare provider before taking these medicines. Also, talk with your provider if you have had a stomach ulcer or gastrointestinal bleeding.
• Use safe lifting methods. Do not lift anything heavier than 15 pounds until all of the pain is gone.

Follow-up care

Follow up with your healthcare provider, or as advised. You may need physical therapy or additional tests.

If X-rays were taken, a radiologist will look at them. You will be told of any new findings that may affect your care.
