Sciatica During Pregnancy: Causes and Relief

Understanding the shooting, burning, or numbing pain that can travel from your low back down your leg.

That electric jolt down your leg isn’t something you have to just white-knuckle through for the rest of your pregnancy.

Somewhere in the second or third trimester, a lot of pregnant people experience a new and unwelcome sensation: a sharp, shooting, sometimes burning pain that starts in the low back or buttock and travels down the back of one leg. This is sciatica, and while it’s common in pregnancy, it’s not something you simply have to live with until delivery.

At Ray of Light Chiropractic in Topsfield, sciatic pain is one of the most common reasons pregnant patients come to see us, and it’s often very responsive to the right kind of care.

What Is Sciatica?

The sciatic nerve is the longest nerve in your body, running from your low back, through your pelvis and buttock, and down the back of each leg.

When something compresses or irritates this nerve, it can cause pain, tingling, numbness, or weakness anywhere along its path.

Why Pregnancy Increases the Risk of Sciatica

• Postural shifts as your growing belly changes your center of gravity
• Relaxin, a pregnancy hormone that loosens ligaments, which can allow the pelvis to shift and put pressure on the nerve
• The piriformis muscle, located deep in the buttock, tightening and irritating the nerve as it passes nearby
• Uneven pelvic alignment, which can pinch or compress the nerve on one side

True Sciatica vs. General Low Back Pain

Signs It’s Likely Sciatica

• Pain travels down the leg, not just staying in the low back
• Tingling, numbness, or a burning sensation along the path of the pain
• Usually one-sided
• Sitting or standing for long periods tends to worsen it

When to Call Your Provider Right Away

• Sudden weakness in the leg or foot
• Loss of bladder or bowel control
• Numbness in the inner thighs or groin (saddle numbness)

These last three symptoms are rare but warrant an immediate call to your OB or midwife.

How Chiropractic Care Helps With Pregnancy Sciatica

At Ray of Light Chiropractic, we focus on identifying exactly where the compression is coming from — often the pelvis, sometimes the piriformis muscle — and use gentle, pregnancy-safe techniques to relieve that pressure.

Because sciatica in pregnancy is so frequently tied to pelvic imbalance, addressing that root cause tends to bring more lasting relief than stretching alone.

What a Visit Typically Involves

1. A conversation about where exactly the pain travels and what makes it better or worse
2. A gentle assessment of pelvic alignment and muscle tension
3. Pregnancy-safe adjustments aimed at relieving nerve compression
4. Home stretches and positioning guidance

Things You Can Try at Home

• Sleep with a pillow between your knees to keep the pelvis level overnight
• Avoid sitting for long stretches without getting up and moving
• Gentle piriformis stretches, as tolerated
• A pregnancy support belt for extra pelvic stability during the day

A note from Dr. Laura: Sciatica in pregnancy can feel discouraging, especially when you’re already managing so much physical change. The good news is that this is one of the areas where gentle chiropractic care tends to make a genuinely noticeable difference.

Frequently Asked Questions

Is sciatica common during pregnancy?

Yes, sciatica is a common complaint during pregnancy, largely due to postural shifts, loosened ligaments from the hormone relaxin, and pelvic misalignment that can put pressure on the sciatic nerve.

What does pregnancy sciatica feel like?

It typically feels like a sharp, shooting, or burning pain that starts in the low back or buttock and travels down the back of one leg, sometimes with tingling or numbness along the path.

Can chiropractic care help pregnancy sciatica?

Yes. Gentle, pregnancy-safe chiropractic care can address the pelvic imbalance or muscle tension often behind sciatic nerve compression, providing relief that tends to last longer than stretching alone.

When should I be concerned about sciatica during pregnancy?

Sudden leg weakness, loss of bladder or bowel control, or numbness in the inner thighs are rare but serious signs that require an immediate call to your OB or midwife.

Does sciatica go away after pregnancy?

For many people, sciatica improves significantly once the baby is born and pelvic alignment stabilizes, though ongoing care may be helpful if the underlying imbalance doesn’t fully resolve on its own.

What side does pregnancy sciatica usually affect?

It’s most often one-sided, though which side is affected can vary and, in some cases, may switch sides as pregnancy progresses and pelvic positioning shifts.
