How Pregnancy Can Impact Existing Back Problems

Last Updated on October 20, 2026 by Successful Black Parenting Staff

Back pain during pregnancy is one of the most common complaints expectant parents bring to their providers, and it can feel even harder when you already live with a back condition. Here is what changes in your body, what usually helps, and when to call your doctor or midwife.

Pregnancy can be a wonderful, life-changing experience. Granted, the life-changing part comes later, but this is definitely the introduction. And it’s often (but not always) difficult on its own; perhaps it’s nature’s way of preparing us for what comes next.

But while many women have difficult pregnancies, those with pre-existing back problems tend to have the worst time. Sure, it’s a joyful time, too, but that doesn’t make it easy on the body. In fact, the changes that keep a pregnancy healthy often push your spine and surrounding muscles into territory they weren’t designed for—at least not without complaint.

That said, there are ways to keep pain under control, and no, you’re not stuck suffering through it. You have plenty of ways to make it more manageable.

Why Pregnancy Ups the Pressure on Your Back

When your body starts changing to carry the extra weight, the mechanics of how you stand, walk, and even sleep also start to change. For example, your center of gravity moves forward. Your lower back curves more as well. Those changes might be minor for someone with a healthy spine, but if you’ve had disc issues, chronic strain, or a past injury, the new posture can magnify every weak point and make the pain a near-constant presence.

Add in the weight gain—usually 25 to 35 pounds, according to CDC data—and you’ve got more load pressing down on the lumbar region. But it’s not just weight. Pregnancy hormones like relaxin loosen the ligaments in your pelvis for delivery, so, while beneficial, they also make other joints, including those in your spine, less stable. And less stability means your muscles have to work harder, and fatigue sets in faster.

The Pain Patterns You Might See + What to Do

Some women notice a steady ache by midday. Others get sharper pain shooting down one leg; classic sciatica, which happens when the sciatic nerve gets compressed. Many women also find it painful to stand for long stretches.

Likewise, if you’ve had herniated discs, degenerative disc disease, or past spinal surgery, you can expect those areas to be more sensitive during your pregnancy. However, if you experience persistent or severe pain (especially if you also have numbness or weakness in your legs), this is something you should take very seriously and seek medical help.

Don’t ignore pain that’s getting worse, making it hard to move, or causing tingling or numbness. Your doctor may suggest physical therapy, targeted exercises, or medication that’s safe during pregnancy.

If problems continue after delivery, or if there’s clear nerve compression, procedures like spinal decompression surgery (lumbar decompression) might be discussed. This type of surgery relieves pressure on the spinal cord or nerves and can be life-changing for people whose pain hasn’t responded to other treatments.

Everyday Adjustments That Help

If you deal with relatively mild back pain, a few targeted changes in how you move and rest can make a big difference:

• Be conscious of your posture: Shoulders back, pelvis neutral, feet planted. Whenever you’re sitting, use a chair with real lumbar support. Fixing posture takes a while, but reminding yourself to be conscious of it and then making appropriate changes will get you there with perseverance.
• Lift with your legs: When you’re lifting things, be careful. Always bend your knees, not your back, and keep whatever you’re lifting close to your body.
• Sleep in alignment: Mattresses aren’t cheap (good ones at least), but it’s an investment your back will appreciate. A firm one helps. Likewise, when you’re side sleeping, place a pillow between your knees to keep your hips and spine in line.
• Stay active: When you’re pregnant and on top of it have back pain, the last thing you probably want to do is be more active. Understandable, but being active absolutely helps. Walking, swimming, or other low-impact exercises help maintain muscle support for your spine. However, it’s best to run plans by your healthcare provider first.
• Alternate heat and cold: When things get tough, use heating pads and cold showers. Heat relaxes tight muscles; cold eases inflammation.

When to Call Your Provider About Back Pain During Pregnancy

The American College of Obstetricians and Gynecologists (ACOG) notes that back pain is very common in pregnancy, but some symptoms need prompt attention. Call your provider right away, or seek urgent care, if you notice:

• Back pain with fever, burning when you urinate, or pain in your side, which can signal a kidney infection
• Rhythmic cramping or pain that comes and goes, which can be a sign of preterm labor
• Vaginal bleeding or a gush or trickle of fluid
• Numbness, tingling or weakness in your legs, or new trouble controlling your bladder or bowels
• Severe pain after a fall or injury
• Pain that keeps getting worse or stops you from walking or sleeping

Trust your instincts. If something feels wrong, say so clearly and ask your provider to explain what they are checking for. You deserve to be heard.

Safe Ways to Ease Back Pain During Pregnancy

• Gentle movement. ACOG recommends about 150 minutes of moderate activity a week for most healthy pregnancies; walking, swimming and stationary cycling are good options. See ACOG’s guide to exercise during pregnancy and check with your provider first.
• Supportive shoes. Low heels with good arch support are easier on your back than high heels or completely flat shoes.
• Belly support. A maternity support belt can take some strain off your lower back later in pregnancy.
• Physical therapy. A physical therapist trained in prenatal care can teach exercises that strengthen your core and hips safely.
• Ask before taking anything. Check with your provider before using any pain reliever, cream or supplement, even ones sold over the counter.

Some parents also ask about chiropractic care. Our article on when pregnant women can go to the chiropractor covers what to know before you book.

Questions to Ask at Your Next Prenatal Visit

• Is my back condition likely to get worse as my pregnancy progresses?
• Which exercises and stretches are safe for me right now?
• Can you refer me to a physical therapist who works with pregnant patients?
• Which pain relief options are safe for me and my baby?
• Does my back condition affect my labor or delivery options?

Regular checkups are where these conversations happen, so keep up with your appointments. Our Q&A on early prenatal care for Black families explains what to expect, and when you are ready to move again after birth, see when you can return to exercise after childbirth.

Planning Ahead Makes a Difference

If you know your back isn’t starting from a strong place, don’t wait until the pain hits. Strengthen your core muscles before pregnancy if possible, work with a provider who understands your history, and keep your daily movements as spine-friendly as possible. Back pain might be common during pregnancy, but it’s not something you have to accept as your “new normal.” With the right habits and timely medical input, you can protect your spine while focusing on what matters: bringing your baby into the world without letting your back dictate the entire experience.
