Sciatica affects roughly 5% to 10% of people with low back pain. It is a painful condition that affects the sciatic nerve, the largest nerve in the body. It can cause discomfort that radiates from the lower back down to the legs, often making simple movements difficult. While there are several ways to manage sciatica, some people consider seeing a chiropractor for relief. But is it actually effective? Can a chiropractor help with sciatica?
A review of 47 randomised controlled trials involving over 9,000 people with chronic low back pain found that spinal manipulative therapy (SMT), a core technique used by chiropractors, works just as well as other recommended treatments like exercise or physical therapy for short-term pain relief. It also provided a small but clinically meaningful boost in function. When compared to treatments that aren't usually recommended, SMT offered even greater improvement in movement and daily functioning.
Side effects were generally mild, such as temporary soreness, and serious risks were rare. One study of 183 participants found no increased chance of adverse effects when comparing SMT to placebo treatment.
While these studies focused on chronic back pain in general (not just sciatica), the overlap in symptoms means the findings are still helpful when considering chiropractic care as part of a sciatica management plan.Let’s explore what causes sciatica, when it might be time to see a chiropractor, and what to expect if you do.
Sciatica isn't a condition in itself. It’s a symptom of an underlying issue affecting the sciatic nerve, the largest nerve in the human body. This nerve runs from the lower back down through the hips, buttocks and each leg. When it's compressed, irritated or inflamed, it can lead to pain, tingling, numbness or weakness along its path.Here are some of the most common causes, backed by current scientific understanding:
This is the most frequent cause of sciatica, accounting for up to 90% of cases. It occurs when the soft, gel-like centre of a spinal disc (nucleus pulposus) pushes through a tear in the outer layer, compressing or irritating nearby nerve roots.
Conditions like spondylolisthesis, where one vertebra slips forward over another, can misalign the spine and pinch the sciatic nerve. Postural deviations from long-term habits or muscular imbalances may also alter spinal alignment and contribute to nerve irritation.
Research shows that osteophyte formation is a significant contributor to lumbar spinal stenosis, particularly foraminal stenosis, which is a common cause of nerve root compression. Bony growths (osteophytes) that develop from osteoarthritis or spinal degeneration can narrow the intervertebral foramina, the passageways where nerve roots exit the spine. When this occurs in the lower back, it can compress the sciatic nerve roots, potentially leading to sciatica symptoms.
With age, intervertebral discs lose hydration and height, which can narrow the space through which nerves exit. This degeneration can lead to mechanical compression or chemical inflammation of the sciatic nerve.
Although less common, tightness or spasm of the piriformis muscle in the buttock can irritate the sciatic nerve, particularly when the nerve runs through or beneath this muscle. This is often considered a non discogenic cause of sciatica.
Lumbar spine injury can result from various types of trauma, including falls, car accidents, sports injuries or improper lifting techniques. Such traumatic events can cause damage to the spinal structures, like the intervertebral discs, ligaments or vertebrae, in the lower back. When these structures are injured, they may shift, tear or swell, which can directly compress or irritate the nerve roots that form the sciatic nerve. This compression is a common cause of sciatica, often leading to sharp, radiating pain, numbness or tingling that travels from the lower back down one leg.
Sedentary behaviour, especially when combined with poor posture and ergonomics, can place excessive pressure on your spinal discs and disrupt the natural balance of muscles supporting your spine. Maintaining these positions over long periods increases strain on the lower back (lumbar region) and causes spinal structures to bear more weight than they’re designed for. This added stress can compress nerve roots, leading to symptoms like pain, numbness or tingling. It can also increase the risk of low back pain and nerve irritation, such as sciatica. Research%20%5B2%5D.) consistently links prolonged sitting and chronic poor posture with these negative effects on spinal health and overall quality of life.
You might consider seeing a chiropractor if your symptoms show any of these signs:
A chiropractor focuses on the musculoskeletal system, particularly the spine, to relieve nerve irritation and improve function. For sciatica, their role may include:
Chiropractors use a variety of evidence-informed, hands-on techniques to help alleviate sciatica symptoms. The goal is to reduce pressure on the sciatic nerve, restore spinal mobility and support the body’s natural healing mechanisms. Here’s a breakdown of commonly used methods and the science behind them:
This core chiropractic technique involves targeted, controlled force applied to specific spinal joints to correct misalignments, improve joint mobility and relieve nerve irritation. Several studies suggest that spinal manipulation can provide moderate relief for acute and chronic lower back pain, including sciatica.
Chiropractors often alternate between heat and cold to manage inflammation and promote healing. Evidence suggests that cold therapy (cryotherapy) can help reduce acute inflammation and numb nerve pain, while heat may increase circulation and relax tight muscles.
Targeted stretching helps lengthen tight muscles that may be compressing the sciatic nerve, such as the piriformis or hamstrings. Chiropractors often prescribe tailored exercises to improve flexibility and strengthen supporting musculature, which can help prevent flare-ups.
Therapeutic ultrasound uses high-frequency sound waves to penetrate deep tissues, promoting blood flow, reducing inflammation and encouraging tissue repair. It’s sometimes used as an adjunct treatment for sciatica and other soft tissue conditions.
This involves using low-level electrical currents to stimulate muscles and nerves. It can help reduce muscle spasms, improve circulation and block pain signals. Transcutaneous electrical nerve stimulation (TENS) has shown some effectiveness in managing lower back and sciatic pain.
Chiropractors may also use hands-on techniques like trigger point therapy, myofascial release or massage to ease muscle tension, reduce pain and improve mobility. These methods can support spinal adjustments and relieve compensatory muscle strain.
A typical first visit may include:
Seeing a chiropractor for sciatica may offer several benefits, especially for those looking to avoid medication or surgery. These potential advantages go beyond pain relief and can support long-term recovery and better spine health.
Chiropractic care isn’t suitable for everyone. It may not be recommended for:
Always consult your GP or specialist before starting chiropractic treatment, especially if you have an existing medical condition.
Chiropractic care is one possible way to manage sciatica symptoms, especially if you're looking for a drug-free approach. While it doesn’t suit everyone, it may offer relief by targeting the underlying cause of nerve pressure. If your symptoms persist or worsen, speak to a healthcare provider to determine the best treatment for your situation.
