Sciatica
Few things get your attention quite like pain that shoots down your leg. If you are dealing with sciatica — that burning, aching, or electric pain that travels from your lower back or buttock into your thigh or entire leg — you already know how much it can disrupt your daily life. Sitting hurts. Standing hurts. Even finding a position to sleep in can feel impossible. Understanding what is happening and what can be done about it is the first step.
What Is Sciatica, Exactly?
Sciatica is not a diagnosis in itself — it is a description of a pattern of symptoms. The term refers to pain that follows the path of the sciatic nerve, which runs from the lower back through the buttock and down the back of each leg. It is the largest nerve in the body, roughly the thickness of your little finger, and when it becomes irritated or compressed, the pain can travel a long way.
The symptoms can vary significantly from person to person:
- Pain — ranging from a deep ache in the buttock to sharp, shooting, or burning pain that runs down the back or side of the leg, sometimes reaching the foot
- Tingling or pins and needles — often in the calf, foot, or toes
- Numbness — a patch of reduced feeling somewhere along the leg or foot
- Weakness — the leg may feel unreliable, or you might notice difficulty lifting your foot or pushing off when walking
- Positional sensitivity — symptoms that change significantly depending on whether you are sitting, standing, walking, or lying down. Many people find sitting is the worst position
Because sciatica describes a symptom pattern rather than a single condition, the critical question is always: what is irritating the nerve? The answer shapes the approach.
What Causes Sciatic Nerve Irritation?
Several different structures can put pressure on or irritate the sciatic nerve. The most common include:
- Disc bulge or herniation — the most well-known cause. The soft centre of a spinal disc pushes outward and presses against the nerve root where it exits the spine. This is more common in the lower lumbar segments (L4/5 and L5/S1)
- Foraminal stenosis — narrowing of the bony opening through which the nerve exits the spine, often related to degenerative changes or joint inflammation
- Piriformis tension — the piriformis is a deep buttock muscle that sits close to (and in some people, directly over) the sciatic nerve. When this muscle becomes tight or irritated, it can compress the nerve and produce symptoms that mimic disc-related sciatica
- Joint dysfunction — altered mechanics in the lumbar spine or sacroiliac joint can change how load is distributed and contribute to nerve irritation
An important thing to know: many disc bulges are asymptomatic. Research has shown that a significant proportion of people with no pain at all have disc bulges visible on MRI. The presence of a disc bulge on a scan does not necessarily mean it is the source of your symptoms, which is why a thorough clinical assessment — testing how you move, where the pain reproduces, and how the nerve is functioning — is often more informative than imaging alone.
How Chiropractic Care May Help
Current evidence supports conservative management, including manual therapy, as an appropriate first-line approach for most presentations of sciatica. What that looks like depends on what we find in your assessment — the cause, the severity, your tolerance, and how your body responds.
Care may include:
- Lumbar mobilisation — careful, graded techniques to improve movement in the lower spine and reduce pressure around the affected nerve. In acute sciatica, these are typically very low-force and focused on positions that give the nerve more room
- Directional preference exercises — specific movements (often extensions or lateral shifts) that may help centralise your symptoms — meaning the pain retreats from the leg back toward the lower back. When these work, they can provide meaningful relief and are something you can repeat at home throughout the day
- Soft tissue therapy — addressing tension in the piriformis, gluteal muscles, and other structures around the hip and pelvis that may be contributing to nerve compression or irritation
- Activity modification advice — practical guidance on sitting positions, sleeping positions, and how to move in ways that reduce load on the nerve while you recover. Sometimes small changes — like how you get in and out of a car, or whether you sit with a rolled towel behind your lower back — can make a noticeable difference
- Progressive rehabilitation — as your symptoms settle, gradually building strength, mobility, and confidence so you can return to your normal activities. This phase is important for reducing the likelihood of recurrence
Sciatica often requires patience. Some people notice improvement quickly; for others, recovery unfolds over weeks. We monitor your progress closely, adjust the approach as needed, and are upfront with you if we think a referral for imaging or another opinion would be appropriate.
What to Expect During Recovery
One of the most common questions people with sciatica ask is how long it will take to get better. The honest answer is that it varies — depending on what is causing the nerve irritation, how long it has been present, and your individual circumstances.
A few things that are helpful to know:
- Centralisation is a good sign. If your pain starts to retreat from the foot or calf back toward the buttock or lower back, this generally indicates that things are improving — even if the back pain itself temporarily feels worse
- Movement is usually helpful. While it may feel counterintuitive, gentle movement — particularly walking — is generally encouraged. Prolonged bed rest is not recommended for sciatica and can sometimes make things worse
- Flare-ups do not mean damage. Sciatica recovery is not always linear. You may have days that feel better and days that feel worse. A bad day does not mean you have gone backwards — it often means the nerve is still sensitised and needs more time
- Sleep can be challenging. Finding a comfortable sleeping position with sciatica can take some experimentation. Lying on your back with a pillow under your knees, or on your side with a pillow between your knees, are positions that many people find more comfortable
We will talk through realistic expectations at your first visit, and keep you informed as we go. The goal is always to help you understand what is happening, feel supported through the process, and get back to doing the things that matter to you.
When to Seek Urgent Care
The majority of sciatica can be managed conservatively and does not indicate anything dangerous. However, there is a rare but serious condition called cauda equina syndrome that requires immediate medical attention. Please go to your nearest emergency department or call 000 if you experience:
- Loss of bladder or bowel control — inability to urinate, or incontinence
- Numbness in the saddle area — the inner thighs, groin, buttocks, or genitals
- Progressive weakness in the leg or foot — particularly foot drop (difficulty lifting the front of your foot)
- Severe, unrelenting pain that does not respond to any change in position
Cauda equina syndrome is uncommon, but it needs to be acted on quickly. Do not wait to see if these symptoms resolve on their own.
