Understanding Sciatica: Symptoms, Causes & Physiotherapy Treatment
Sciatica is a common condition that can cause lower back pain, tingling, numbness, or weakness that travels from the lower back into the buttock and down the leg. While sciatica can be uncomfortable and sometimes quite painful, many people recover well with the right management and gradual return to movement.
Understanding what causes sciatica and how to manage sciatic nerve pain can help you feel more confident and get back to the activities you enjoy.
What Is Sciatica?
Sciatica refers to symptoms caused by irritation or compression of the sciatic nerve or the nerve roots that contribute to it. The sciatic nerve is the largest nerve in the body and runs from the lower back through the buttocks and down the back of each leg.
Sciatica typically affects one side of the body and may cause:
Pain that travels from the lower back or buttock into the leg
Tingling or pins and needles
Numbness
A burning or electric-like sensation
Weakness in the leg or foot
Increased symptoms with certain movements or positions
Symptoms can vary significantly from person to person. Some people experience mainly leg pain, while others may have a combination of lower back and leg symptoms.
What Causes Sciatica?
Sciatica can develop for several different reasons. Common causes of sciatic nerve pain include:
Disc irritation: A bulging or herniated disc can irritate a nearby nerve root.
Changes in the spine: Age-related changes, such as arthritis, can sometimes narrow the spaces where nerves travel.
Spinal stenosis: Narrowing around the spinal canal or nerve pathways can place pressure on the nerves.
Spondylolisthesis: One vertebra can shift relative to another, potentially affecting nearby nerves.
Muscle and movement-related factors: Changes in movement patterns, muscle strength, and physical activity can contribute to symptoms in some people.
Importantly, the cause of sciatica isn't always obvious, and imaging findings do not always directly match the severity of someone's symptoms. A thorough assessment can help identify the factors contributing to your symptoms and guide appropriate sciatica treatment.
What Can Make Sciatica Worse?
Sciatica symptoms can be influenced by a range of factors. Depending on the individual, symptoms may become more noticeable with:
Prolonged sitting
Repeated bending or lifting
Certain twisting movements
Reduced physical activity
Sudden increases in activity
Poor sleep or fatigue
Stress and reduced confidence with movement
It's important to remember that experiencing pain does not necessarily mean you are causing further damage. In many cases, gradually returning to movement and activity is an important part of recovery.
How Is Sciatica Treated?
The good news is that most people with sciatica improve with conservative treatment and do not require surgery. Physiotherapy for sciatica can play an important role in helping you understand your symptoms, manage pain, and gradually return to your normal activities.
Treatment may include:
Movement and Exercise
A physiotherapist can prescribe individualised exercises based on your symptoms, physical capacity, and goals. This may include mobility exercises, strengthening, and graded activity to help restore confidence and function.
Strengthening
Improving the strength of the muscles around the hips, pelvis, and trunk can help support your movement and improve your ability to complete everyday activities. Exercises can be gradually progressed as your symptoms and strength improve.
Education and Advice
Understanding your symptoms can be an important part of recovery. Your physiotherapist can provide advice about activity modification, pacing, lifting techniques, and strategies to gradually return to work, exercise, and daily activities.
Hands-On Treatment
Depending on your individual presentation, hands-on techniques such as soft tissue massage or joint mobilisation may be used alongside exercise to help manage pain and improve movement. These treatments are generally used to support active rehabilitation rather than as a standalone treatment.
Graded Return to Activity
If pain has limited your usual activities, your physiotherapist can help you develop a gradual plan to return to walking, exercise, work, or hobbies. The aim is to build your confidence and physical capacity without doing too much too quickly.
When Should You See a Physiotherapist for Sciatica?
If you're experiencing ongoing lower back or leg pain, tingling, numbness, or difficulty returning to your usual activities, a physiotherapist can assess your symptoms and develop a personalised treatment plan. Early guidance can help you understand your condition, stay active where appropriate, and build your strength and confidence as you recover.
You should seek urgent medical attention if you develop new or worsening significant weakness in your legs, numbness around the groin or saddle area, or changes to bladder or bowel control, as these can be signs of a more serious condition requiring immediate assessment.
