Sciatica: Why That Shooting Leg Pain Happens and How to Treat It

Few pains are as alarming as a sudden, electric jolt that travels from your lower back or buttock down into your leg. Many people who feel it for the first time fear the worst. The reassuring truth is that this pain, known as sciatica, is common, usually not dangerous, and in most cases settles well with time and physiotherapy. Here is what is actually happening and what you can do about it.

Sciatica Is a Symptom, Not a Diagnosis

This is the single most important thing to understand. Sciatica is not a disease in itself. It is the name for a set of symptoms, pain, tingling, numbness or weakness, that travel from the lower back or buttock down the leg along the path of the sciatic nerve. That nerve is the longest in your body, running from the lower spine through the buttock and down the back of each leg. When it is irritated or compressed anywhere along the way, you feel it down the line.

Because sciatica is a symptom, the useful question is not simply how to stop the leg pain, but what is irritating the nerve in the first place.

What Causes Sciatica

The most common cause is a disc bulge or herniation in the lower back pressing on a nerve root as it exits the spine. The soft cushion between two vertebrae shifts and irritates the nearby nerve. Other causes include age-related narrowing of the spaces the nerves pass through, and sometimes tight or irritable muscles such as the piriformis in the buttock pressing on the nerve nearby.

Typical features include pain that is often worse down the leg than in the back itself, symptoms usually on one side, and pain that can be provoked by sitting, coughing or sneezing. Tingling, pins and needles, or numbness in part of the leg or foot are common too.

The pain can feel frightening, but a nerve that is irritated is not a nerve that is broken. Most sciatica calms down with the right movement and time.

The Reassuring News About Recovery

For the great majority of people, sciatica improves over a period of weeks. The body reabsorbs disc material and inflammation settles. The most helpful things you can do are to stay as active as your pain allows, avoid long spells of bed rest, and keep gently moving. Prolonged rest tends to stiffen the back and slow recovery.

Physiotherapy supports this natural recovery and often speeds it up. Treatment usually blends gentle movement and specific exercises, nerve mobilisation techniques that help the nerve glide freely again, and progressive strengthening of the back, core and hips to take pressure off the area and reduce the chance of it returning. You can learn more about how we manage this on our back pain page, and our musculoskeletal and sports physiotherapy service is built exactly for problems like this.

Red Flags: When to Seek Emergency Care

Sciatica is usually not an emergency, but a small number of symptoms need urgent medical attention. Go to a hospital or seek emergency care straight away if you experience any of these:

• Numbness or tingling around the groin, genitals or saddle area (the parts that would touch a saddle)
• Loss of control of the bladder or bowel, or difficulty passing urine
• Severe or rapidly worsening weakness in the leg or foot
• Numbness or weakness spreading to both legs

These can signal serious pressure on the nerves that requires prompt treatment. They are uncommon, but they are the reason to act immediately rather than wait.
