If you’re pregnant and feeling a sharp, shooting pain down your leg, you’re not imagining it, and you’re not alone. Sciatica during pregnancy is one of the most common complaints we hear at My Chiropractic Place, and gentle, pregnancy-safe chiropractic care can often bring real relief. Here’s what causes it, how to spot it, and how our clinics approach it.
What Is Sciatica During Pregnancy?
Sciatica happens when the sciatic nerve, the longest nerve in your body, gets irritated or compressed. It runs from your lower back, through your hips, and down each leg. When something presses on it, pain can travel the whole way down.
During pregnancy, doctors often use the term lumbar radiculopathy. It’s not quite the same thing as sciatica: radiculopathy refers specifically to irritation at the nerve roots inside the lower spine, while sciatica can occasionally start further along the nerve’s path, such as from a tight piriformis muscle in the buttock. In pregnancy, though, the spine and pelvis are usually where the pressure begins, so the two terms often describe the same experience.
Symptoms of Pregnancy-Related Nerve Pain
Every pregnancy is different, but most women describe a similar pattern of symptoms:
- A burning or shooting pain that starts in the lower back or buttock
- Pain that travels down one leg, sometimes reaching the foot
- Tingling or a “pins and needles” feeling
- Numbness or muscle weakness in the leg
- Pain that gets worse when you sit, stand up, cough, or sneeze
Most women feel this on just one side of the body. If it’s on both sides at once, or it comes with numbness around your groin or trouble controlling your bladder, that’s a different situation.
What Causes Sciatica During Pregnancy?
Relaxin and Loosening Ligaments
Your body produces a hormone called relaxin during pregnancy. It loosens your joints and ligaments to prepare for birth, which is helpful in labour but can leave your lower back and pelvis less stable in the meantime. That instability can put extra pressure on nearby nerves.
A Growing Belly, Shifting Posture
As your baby grows, your centre of gravity shifts forward. Most women adjust by leaning back slightly, which changes how weight sits through the lumbar spine. Combined with the added weight, this can compress the nerve roots that innervate the sciatic nerve.
When It Usually Starts
Low back pain affects roughly half of all pregnant women, and Australian research puts the figure at a similar level, with rates in other studies ranging anywhere from 25 to 90 per cent depending on how it’s measured. Sciatic-type pain tends to appear in the second half of pregnancy and often becomes more noticeable in the third trimester, as the baby settles lower into the pelvis.
Is Chiropractic Care Safe During Pregnancy?
Chiropractic techniques used for pregnant patients are adapted for a changing body. Treatment tables can be modified to reduce pressure on the abdomen, and adjustments are gentler than those used in a typical technique outside pregnancy. A review of manual therapies for pregnancy-related back and pelvic pain found supportive evidence for easing discomfort with a low rate of adverse effects. However, the authors noted that study quality varies and more high-quality research is still needed.
That’s an honest, useful summary: many women find real relief, and serious complications are rare, but no treatment works the same for everyone. A proper assessment before starting care matters, which is exactly what happens at both our clinics before any adjustment is made.
A Real Case: Recovering from Lumbar Radiculopathy During Pregnancy
The following case, published in a peer-reviewed chiropractic journal, illustrates what recovery can look like for one patient. It’s a single case, not a guarantee of results, but it’s a useful, real-world example of how quickly some women respond to care.
During pregnancy, the expecting mother endures numerous physical stresses and strains that often lead to musculoskeletal aches and pains. One prevalent symptom is lumbar radiculopathy, which manifests as pain, numbness, or tingling radiating down the leg and may also include weakness in the affected limb. This condition typically arises from irritation of the smaller nerves (nerve roots) exiting the spine in the lumbar region of the lower back.
A case study published in the Journal of Chiropractic Medicine explored the effectiveness of chiropractic care for lumbar radiculopathy in a 26-year-old woman in her second trimester of pregnancy. She experienced severe lower back pain that radiated to both hips and her right leg. She also reported tingling extending down her right lower leg to the top of her right foot.
Before treatment, a comprehensive evaluation was conducted to rule out more serious conditions, leading to a diagnosis of lumbalgia (lower back pain) with associated radiculopathy. The woman received her first chiropractic treatment and experienced immediate relief. By her eighth visit, she reported a complete resolution of her symptoms.
This case underscores the high efficacy of chiropractic care in managing lumbar radiculopathy during pregnancy. In addition to its effectiveness, chiropractic care is extremely safe for most expecting mothers and their fetuses, offering a natural and non-invasive treatment option for alleviating the discomforts associated with pregnancy.

It’s worth being clear about what this case does and doesn’t show. It’s one woman’s outcome, not a general finding, and results like an eight-visit full recovery won’t happen for everyone. What it does show is that chiropractic care is a genuine option worth discussing with your practitioner, alongside the safety picture outlined in the research above.
How My Chiropractic Place Can Help
Both our Melbourne clinics use the Gonstead method exclusively, a precise, hands-on approach to finding exactly where a nerve is under pressure before adjusting. We also offer in-house X-ray imaging, so if further assessment is needed, you’re not sent elsewhere and waiting on results.
Dr Addie has practised since 2005. As an RMIT graduate trained in the Gonstead method, he works directly with patients from assessment through to ongoing care, including pregnancy-safe adjustments for local mums-to-be.
Dr Nam Nguyen has led the clinic since 2007, offering the same Gonstead-based, direct-access care to families in Melbourne’s west. Medicare Care Plans are accepted at both locations.
When to See a Doctor
Most pregnancy sciatica is manageable and improves with time and the right care. Still, some symptoms need urgent medical attention rather than a chiropractic visit first:
- Sudden loss of bladder or bowel control
- Numbness around your inner thighs or groin
- Rapidly worsening weakness in your leg or foot
- Severe pain that comes on suddenly and doesn’t ease
If any of these happen, contact your doctor or maternity hospital straight away.
Frequently Asked Questions
Is sciatica during pregnancy common?
Yes. Low back pain affects around half of pregnant women, and sciatic-type nerve pain is a common variation of this, especially from the second trimester onward.
Can chiropractic care harm the baby?
Chiropractors trained in pregnancy care use techniques adapted for a pregnant body, including tables that avoid pressure on the abdomen. Always mention your pregnancy and any complications before treatment begins.
When does sciatica during pregnancy usually go away?
Many women see improvement within weeks of starting care, and symptoms often resolve fully after birth, though timing varies from person to person.
Should I see a chiropractor or a doctor first?
If your symptoms are mild to moderate, a chiropractor can assess you directly. If you notice any red flag symptoms listed above, see a doctor or go to the hospital first.
