Sciatica: Causes, Symptoms and the Best Treatment Options

Sciatica is one of the most common causes of leg pain, affecting millions of people each year. It occurs when the sciatic nerve, which runs from your lower back down each leg, becomes irritated or compressed. The pain can range from mild discomfort to severe, shooting pain that makes walking or sitting difficult.

At Physio Network, we provide expert sciatica treatment in Hertfordshire, helping patients reduce pain, improve mobility, and return to their daily activities through personalised home physiotherapy.

What Causes Sciatica?

Sciatica is a symptom rather than a condition itself. Common causes include:

Herniated (slipped) disc
Degenerative changes in the spine
Spinal stenosis
Muscle tightness, particularly the piriformis muscle
Arthritis affecting the lower back
Poor posture or prolonged sitting

Identifying the underlying cause is essential for effective treatment.

Common Symptoms

Symptoms of sciatica may include:

Sharp or burning pain from the lower back into the buttock or leg
Tingling or pins and needles
Numbness in the leg or foot
Muscle weakness
Pain that worsens when sitting, coughing, or sneezing

Sciatica usually affects one side of the body, although the severity varies between individuals.

Sciatica Exercises That May Help

Gentle movement is often better than prolonged bed rest. These sciatica exercises can help reduce stiffness and improve mobility.

Knee-to-Chest Stretch

Lie on your back with your knees bent. Slowly bring one knee towards your chest and hold for 20 seconds. Repeat three times on each side.

Piriformis Stretch

Lie on your back and cross one ankle over the opposite knee. Gently pull the supporting leg towards your chest until you feel a stretch in your buttock. Hold for 20–30 seconds.

Walking

A short walk several times a day helps improve circulation, reduce stiffness, and encourage recovery. Start with a comfortable distance and gradually increase as symptoms improve.

Stop any exercise that causes severe or worsening pain and seek professional advice.

Physiotherapy for Sciatica

Physiotherapy is one of the most effective treatments for sciatica. After assessing your symptoms, a physiotherapist will develop a personalised treatment plan that may include:

Manual therapy
Targeted strengthening exercises
Stretching programmes
Postural advice
Mobility training
Education on preventing future episodes

Treatment focuses on relieving pressure on the sciatic nerve while improving movement and function.

When Should You Seek Medical Advice?

You should seek urgent medical attention if you experience:

Loss of bladder or bowel control
Numbness around the groin or saddle area
Severe weakness in one or both legs

You should also arrange a physiotherapy assessment if your symptoms last longer than two weeks, become progressively worse, or significantly affect your daily activities.
