Sciatica

What is sciatica?
Sciatica is a condition that can lead to pain in the back and legs. It occurs when pain travels along the path of the sciatic nerve. This nerve starts in the lower spine and travels through the hip and buttock and down the back of the leg to the foot.

There is a range of different causes of sciatica. In most cases, the condition gets better over time, either on its own or with treatment.

What are the symptoms of sciatica?
Symptoms of sciatica can include pain, tingling, and numbness in the leg.

Sciatica is felt as nerve pain radiating from the buttock down the back of the leg, often when sitting, sneezing, coughing, or going to the toilet. You may also feel lower back pain and/or tingling, pins and needles, numbness, or weakness in your leg.

Although sciatica pain can be severe, most people find their symptoms improve in time. As sciatica is seen as a more serious low back condition, it’s advisable to see your doctor within the first few days of getting the symptoms. To diagnose sciatica, the doctor will take a medical history and examine your spine and legs.

You should seek medical attention immediately if you have problems controlling your bladder or bowels or have weakness, numbness, or severe pain.

The Royal Australian and New Zealand College of Radiologists recommend that an x-ray or other imaging in response to low back pain is only needed if you have other significant symptoms. If you have sciatica, discuss with your doctor whether imaging is required, which it may or may not be, depending on the circumstances.

What causes sciatica?
The causes of sciatica include spinal injury or trauma, bone spurs or other growths, narrowing of the spinal canal, or tight or swollen muscles in the buttock. In many cases, people can’t pinpoint a specific injury that caused the condition.

Risk factors for sciatica include:

• age-related changes to the spine
• obesity, which can put extra pressure on the spine
• occupations where you twist the spine or pick up heavy loads
• prolonged sitting
• diabetes, which can increase the risk of nerve damage

How is sciatica treated?
The choice of sciatica therapies depends on the length of symptoms and severity of your condition. These therapies include:

• special back care education
• rest
• physical therapies
• medication treatment
• lifestyle changes
• surgery

Mild sciatic usually goes away in time. When you first experience sciatica, 1 or 2 days’ bed rest may be needed. However, it’s important to return to activity as soon as possible to help your spine stay strong.

Sciatica treatment includes pain relief medicines such as paracetamol, anti-inflammatory drugs such as ibuprofen, and physiotherapy. Most people with sciatica get better with conservative treatments such as physiotherapy.

You should see your doctor again self-care measures fail to improve your pain if your pain lasts longer than a week, is severe, or becomes progressively worse.

If your symptoms persist, an injection of anesthetic into the spine may be needed or, in rare cases, surgery.

Can sciatica be prevented?
Looking after your back, managing your weight, and improving your general physical condition can all help prevent sciatica. Doing physical therapy at home, such as muscle-strengthening exercises, can help to prevent sciatica from coming back.
