Pregnancy and sciatica nerve pain: Everything you need to know

Pregnancy is an exciting journey, but it often comes with aches and pains you never expected. One of the most uncomfortable issues many expectant moms face is sciatica nerve pain during pregnancy.

If you’ve ever felt a sharp, shooting pain down your lower back, hip or leg while pregnant, you may already know exactly what this feels like.

The good news? While sciatica during pregnancy can make daily tasks more difficult, it’s also manageable with the right care and a few simple strategies.

Let’s walk through everything you need to know about pregnancy and sciatica nerve pain, including what causes it, how to recognize the symptoms and the best ways to find relief—so you can focus on what really matters: preparing for your little one.

Understanding pregnancy and sciatica nerve pain

Carrying a baby can be hard on your body. As a result, many women experience pain along the sciatic nerve, the largest nerve in your body, which runs from your lower back down through your hips and legs.

When that nerve gets irritated or compressed, you may feel pain, tingling or numbness anywhere along its path. Sciatica pain can wax and wane throughout your pregnancy. It’s very common, especially in the third trimester.

During pregnancy, your body goes through big changes that can make sciatica more likely. Your growing belly shifts your posture and center of gravity, which puts pressure on your lower back. Pregnancy-related weight gain also increases the load on your lower back.

Hormones also play a role. The hormone relaxin, for example, loosens ligaments to prepare for delivery, but it can also make your spine and pelvis less stable, allowing for more nerve irritation.

The result: a combination of physical and hormonal factors that can trigger sciatica pregnancy pain for some moms-to-be.

Sciatica pregnancy symptoms

While sciatica is a common source of back pain for pregnant women, not all back pain during pregnancy is sciatica. Typical pregnancy backaches often feel dull and achy, but sciatica is different.

Here are the most common signs of sciatica during pregnancy:

• Sharp, shooting pain that starts in the lower back or buttock and radiates down one leg
• Numbness, tingling or a “pins and needles” feeling in the leg or foot
• Muscle weakness in the affected leg
• Pain that worsens with certain movements, like standing up, sitting for long periods or rolling over in bed

Symptoms can range from mild to severe and may come and go depending on how active you are.

As an OBGYN, I hear some women describe sciatica during pregnancy as a shooting pain when they try to stand, often occurring in just one leg. If you’ve felt a similar sharp pain, it’s a good idea to talk to your doctor about ways you can find relief.

How to relieve sciatica during pregnancy

If you’re experiencing back or leg pain from sciatica during pregnancy, the first step is to talk with your OBGYN or primary care physician. They can evaluate your symptoms and recommend safe treatment options for you and your baby.

In the meantime, here are some practical tips to ease your pain.

Relax and rest

If you’re experiencing back pain, take is as a sign that you should take a break and relax. There’s probably a lot on your to-do list before the baby’s arrival, but be careful not to overdo it, especially toward the end of your pregnancy. Take it easy when your body signals that it’s time for a break.

Focus on your posture

Be sure to sit up straight and keep your shoulders from curling inward. As your belly grows, it’s easy to lean back or slouch without realizing it.

Standing tall with your shoulders back can take some of the pressure off your lower back and sciatic nerve. Supportive shoes can also help keep your body aligned.

Keep moving

While rest is important, be sure to keep your body moving. Bringing blood flow to your back will help it stay healthy and simple stretches can ease tension around the sciatic nerve. Skip the high intensity workouts for now.

Self-care

Now is the time to prioritize taking care of your body. A few self-care steps at home can help relieve sciatica pain, including:

• Warm bath
• Prenatal massage
• Alternating heating pad and ice pack on your lower back
• Pregnancy-safe pain relievers (ask your doctor)

Exercises for sciatica

Movement is one of the best remedies for sciatica pregnancy pain. But it’s important to stick to safe, low-impact exercises rather than high-intensity or high-impact workouts.

Here are a few exercises for sciatica that may help ease nerve pressure and strengthen supportive muscles.

• Pelvic tilts: Lie on your back with knees bent and feet flat on the floor. Tilt your pelvis upward, gently flattening your lower back against the floor. Hold for a few seconds and release.
• Prenatal yoga stretches: Poses like child’s pose, cat-cow and pigeon stretch can open up tight hips and relieve pressure.
• Walking: Short, gentle walks keep your body moving without putting too much stress on your spine.
• Water aerobics or swimming: Exercising in water supports your body weight, reduces strain and provides natural resistance for strengthening muscles.

Always check with your doctor before starting any new exercises, especially during pregnancy.

Navigate pregnancy with confidence

Pregnancy is a time of growth and excitement. Sciatica during pregnancy is common, but it doesn’t have to steal your joy. With a few simple strategies, you can stay active and feel comfortable as you prepare for the arrival of your little one.
