Why Sciatica Shows Up During Pregnancy (And What You Can Do About It)

If you've ever had a sharp, burning pain start in your lower back or buttock and travel down your leg, you know how uncomfortable sciatica can be. Now imagine dealing with that while you're pregnant.

Pregnancy brings a lot of changes to your body. Your belly grows, your posture changes, your center of gravity shifts, and the muscles and ligaments around your pelvis adapt to support your growing baby.

All of these changes affect how your body moves and handles everyday activities.

For some moms, that means more pressure and irritation around the lower back, hips, and sciatic nerve.

You don't have to simply accept that being uncomfortable is part of pregnancy.

There are ways to support your body and help you move more comfortably. Let's talk about why it happens and what you can do.

Why Does Sciatica Happen During Pregnancy?

The sciatic nerve is the largest nerve in your body. It starts in your lower back, travels through your hips and buttocks, and continues down the back of each leg.

When this nerve becomes irritated or compressed, you may experience pain, burning, tingling, or numbness that travels down one leg. Pregnancy can create several changes that contribute to these symptoms.

Cause 01

Your posture changes

As your baby grows, your center of gravity shifts forward. You may naturally change how you stand, walk, and move to accommodate your growing belly. This can place additional demands on your lower back and pelvis.

Cause 02

Your ligaments become more flexible

Pregnancy hormones, including relaxin, help prepare your body for childbirth by changing the flexibility of connective tissues. This can affect how your pelvis and surrounding joints move and handle stress.

Cause 03

Your body is carrying more weight

Your growing baby, uterus, and changes in body weight all affect how your body distributes pressure. Your hips, pelvis, and lower back are working differently than they were before pregnancy.

Cause 04

Your muscles are working harder

The muscles around your hips, buttocks, and lower back may become tight or overworked. In some cases, irritation around these muscles can contribute to sciatic-type symptoms.

One important thing to understand: Not every pain that travels into your buttock or leg is true sciatica. Pregnancy-related pelvic girdle pain and muscular discomfort can feel similar. Understanding what is causing your symptoms is an important first step.

At New Directions Chiropractic, we work with expecting moms throughout Allen, McKinney, and the surrounding North Dallas area. We understand that pregnancy puts new demands on your body, and we want to help you understand how your body is adapting.

What Can You Do for Sciatica During Pregnancy?

Before looking for a treatment, start by looking at how you're moving throughout the day. Your body is changing. What felt comfortable a few months ago may not feel as comfortable today.

Here are a few things that may help.

1

Keep Moving

Movement is important during pregnancy. Sitting or standing in one position for long periods can make muscle tension and discomfort worse.

  • Taking short walks throughout the day
  • Changing positions regularly
  • Avoiding long periods of sitting
  • Moving within a comfortable range rather than pushing through pain

You don't need an intense workout. Consistent, comfortable movement is a good place to start.

2

Pay Attention to How You Sleep

Sleep can become more challenging as your pregnancy progresses.

Try sleeping on your side with a pillow between your knees. A pregnancy pillow or additional support under your belly may also help you find a more comfortable position.

The goal is to support your hips and lower back so your muscles aren't working overtime while you rest.

3

Try Gentle Movement and Stretching

Some expecting moms find relief with gentle mobility exercises. A few options to discuss with your maternity care provider include:

Supported cat-cow

On your hands and knees, gently round and relax your back within a comfortable range.

Seated figure-four stretch

Sit in a chair and gently cross one ankle over the opposite knee. Only lean forward if it feels comfortable and does not reproduce leg symptoms.

Gentle walking

Take shorter walks throughout the day instead of trying to do everything at once.

Don't force a stretch. If it causes sharp pain, tingling, or symptoms that travel farther down your leg, stop.

4

Use Comfortable Positions and Support

Pay attention to how you stand, sit, and move.

Avoid standing with all your weight shifted onto one hip. When sitting, use support behind your lower back and take breaks regularly.

A warm pack may also help relax tight muscles. Keep the temperature comfortable and avoid overheating.

A Simple Daily Routine

You don't need to make your day complicated. Try building a few simple habits into your routine.

Morning

Take a short walk and do some gentle movement.

Midday

Get up regularly if you've been sitting. Change positions and move around.

Evening

Give yourself time to rest. Use pillows to support your hips and belly.

The goal isn't to do more. It's to help your body handle the demands of pregnancy throughout the day.

How Can a Pregnancy Chiropractor Help?

This is where I think it's important to look at the bigger picture.

Pregnancy changes how your entire body moves and functions. Your pelvis, hips, lower back, muscles, and nervous system are all involved in helping you adapt to those changes.

When an expecting mom comes into our office, I don't want to just look at where something hurts. I want to understand what she's experiencing, how she's moving, and what may be contributing to her discomfort.

Depending on your history and examination, prenatal chiropractic care may include:

Pelvic and spinal assessment

Looking at how your pelvis and lower back move and identifying areas of restricted or uncomfortable movement.

Gentle chiropractic adjustments

Pregnancy-appropriate techniques may be used to address joint movement and help support comfortable movement.

Movement and positioning education

Simple recommendations for sitting, sleeping, standing, and moving throughout the day.

Individualized care

Your needs at 14 weeks may be very different from your needs at 34 weeks. Care should reflect where you are in your pregnancy and what your body is experiencing.

Chiropractic care isn't a guaranteed solution for sciatica, and it isn't appropriate for every cause of leg pain. Some moms benefit from a combination of chiropractic care, physical therapy, exercise, and guidance from their maternity care team. Our goal is to help you understand what's happening and determine what kind of support makes sense.

What Should You Expect at Your First Prenatal Chiropractic Appointment?

If you've never been to a chiropractor during pregnancy, you may have questions about what happens during an appointment. That's completely understandable.

Your first visit should start with a conversation. We'll want to know:

How far along are you?
Where are you experiencing discomfort?
Does the pain travel into your buttock or leg?
What activities make it better or worse?
Have you experienced these symptoms before pregnancy?
Any pregnancy complications or health concerns we should know about?

From there, an appropriate examination may include looking at your posture, movement, pelvic mechanics, and areas of discomfort. If chiropractic care is appropriate, we'll explain what we recommend and why.

Stage What to Expect
Conversation Discuss your pregnancy, symptoms, and health history
Examination Evaluate posture, movement, and areas of discomfort
Care Pregnancy-appropriate chiropractic techniques, when indicated
Home guidance Discuss positions, movement, and activities that may help

You should understand what we're doing and feel comfortable asking questions throughout the process.

What Is the Webster Technique?

If you've been researching prenatal chiropractic care, you've probably come across the Webster Technique.

The Webster Technique is a specific chiropractic analysis and adjustment approach used during pregnancy. It focuses on the sacrum, pelvis, and surrounding structures. It is commonly discussed in prenatal chiropractic because of its focus on pelvic mechanics.

An important clarification

The Webster Technique is not a treatment for sciatica, and it does not guarantee that a baby will turn into a head-down position.

When choosing a chiropractor during pregnancy, ask about their training and experience. A few questions worth asking:

Are you Webster Technique certified?
How much experience do you have working with expecting moms?
What techniques do you use during pregnancy?
How do you modify care as pregnancy progresses?
How will we evaluate whether care is helping?

Dr. Jonathon Harrison at New Directions Chiropractic has been Webster Technique Certified since 2012, holds Pediatric Experience Certification from 2022, and is board certified by the National Board of Chiropractic Examiners. New Directions Chiropractic was also voted Mom Approved 2026 by DFW Child.

We believe expecting moms deserve to understand their care and feel confident in the people helping them along the way.

When Should You Seek Medical Attention?

Most pregnancy-related back and pelvic discomfort is not an emergency. However, certain symptoms should never be ignored.

Contact your maternity care team promptly if you experience:

New or worsening leg weakness
Significant or progressive numbness
Pain following a fall or injury
Fever along with back pain
Regular contractions or cramping
New bladder or bowel difficulties

Seek emergency medical evaluation if you experience:

Loss of bladder or bowel control, numbness around your groin or saddle area, or rapidly progressing leg weakness. These symptoms can indicate a more serious condition that requires immediate evaluation. Chiropractic care is not the appropriate first step.

Also, if you have vaginal bleeding, fluid leakage, or other concerning pregnancy symptoms, contact your maternity care team.

We would rather have you get checked and find out everything is okay than overlook something that needs attention.

Helping Your Body Adapt to Pregnancy

Pregnancy is an incredible process, but that doesn't mean it's always comfortable.

Your body is growing and changing every week. Your muscles, joints, and nervous system are constantly working together to help you adapt.

A family-friendly environment
Individualized attention to your needs and goals

You deserve to understand your body and have a plan for taking care of it.
