Sciatica is one of the most common reasons people search for a physiotherapist, but it’s often misunderstood. It isn’t a diagnosis on its own — it’s a symptom, caused by irritation or compression of the sciatic nerve, the longest nerve in the body. If you’re dealing with sharp, shooting, or burning pain running from your lower back through your buttock and down one leg, physiotherapy is usually one of the first places to start.
What Causes Sciatica?
The sciatic nerve runs from the lower spine, through the buttock, and down the back of each leg. Sciatica happens when something presses on or irritates this nerve along its path. Common causes include:
- A bulging or herniated disc in the lower spine
- Spinal stenosis — narrowing of the space around the nerve
- Piriformis syndrome, where a muscle deep in the buttock irritates the nerve
- Degenerative changes in the spine that can come with age
The pain can range from a dull ache to a sharp, electric-shock sensation, and it’s often accompanied by numbness, tingling, or muscle weakness in the leg or foot.
How Physiotherapy Can Help
Current guidance points to staying active and starting physiotherapy early as a first approach for sciatica, rather than prolonged rest. A physiotherapist’s role is to work out what’s actually irritating the nerve, then build a plan around that specific cause.
A typical assessment looks at:
- Your movement patterns and posture
- Which movements ease or aggravate your symptoms
- Muscle strength, flexibility, and how freely the nerve is moving
- Any signs that need urgent medical review (more on this below)
From there, treatment is usually a mix of:
- Targeted exercises to ease pressure on the nerve and build supporting strength
- Nerve gliding (“flossing”) techniques to help the nerve move more freely through surrounding tissue
- Manual therapy to ease muscle tension contributing to the irritation
- Practical guidance on posture, movement, and daily activities, so day-to-day habits aren’t unknowingly making it worse
What to Expect From a Session
Every case of sciatica is different, so the first session focuses on understanding your pain and what’s driving it rather than following a generic script. Expect to be asked how the pain behaves — what brings it on, what eases it, how it’s affecting sleep and daily activities — before a plan is built around your actual routine.
Exercises That Often Help
What’s appropriate depends on what’s actually driving the symptoms, but common approaches include:
- Gentle nerve glides
- Piriformis and hip stretches
- Core and gluteal strengthening
- Gradually building back up to regular walking
Prolonged bed rest, deep spinal twists, and heavy lifting without guidance are generally best avoided while symptoms are active.
When to Seek Urgent Medical Attention
Sciatica is usually manageable with conservative treatment, but a small number of cases need urgent medical assessment. Seek immediate medical care if you experience:
- Loss of bladder or bowel control
- Numbness in the saddle area (inner thighs, groin, or around the genitals)
- Progressive weakness in both legs
- Sciatica following significant trauma
These can be signs of cauda equina syndrome, a rare but serious condition that requires emergency treatment.
Physiotherapy at Home
For people managing sciatica alongside mobility limitations, getting to a clinic can be part of the problem, not just the pain itself. A home visit means your physiotherapist sees how you actually move around your own space — how you get in and out of your favourite chair, how you manage the stairs — and builds a plan around that reality rather than a clinic setup.
If you’re dealing with sciatica and would like an assessment in the comfort of your own home, get in touch with Bayside Mobile Physio to arrange a visit.
