Pregnancy-Related Back & Pelvic Pain in Oatlands

Somewhere around the second trimester, getting out of bed stops being a simple, one-step process. There's the careful roll onto your side, the push up with your arms, the pause to let your lower back catch up to the rest of you. By the third trimester, it's a full production — and that's before you've even started your day.

If pregnancy has brought along aches in places you never expected — your lower back, your hips, that strange deep pain right at the front of your pelvis — you're in very good company. Studies suggest more than half of pregnant women experience back or pelvic pain at some point. It's common, but that doesn't mean it's something you simply have to grit your teeth through for nine months. Pregnancy-related back and pelvic pain can be influenced by several factors, including changes in load, movement, activity and individual history. The good news is that there are practical ways to manage many musculoskeletal symptoms during pregnancy.

Studies suggest more than half of pregnant women experience back or pelvic pain at some point. It's common, but that doesn't mean it's something you simply have to grit your teeth through for nine months. Most pregnancy-related pain has a clear physical cause, and much of it responds very well to the right kind of gentle, pregnancy-safe care.

Why Pregnancy Causes So Many Aches and Pains

Hormonal changes. Pregnancy involves substantial hormonal changes that affect many tissues throughout the body. Although hormones such as relaxin are often blamed directly for pelvic pain, the relationship is more complicated than simply “loose ligaments causing instability.” Pregnancy-related pain is usually influenced by several factors rather than one hormone alone.

A shifting centre of gravity. As your belly grows, your posture naturally adapts — the lower back curves further forward to keep you balanced, which increases load on the joints and muscles of the lower spine.

Added weight and changing load. Extra weight, carried in a very specific place, changes how load moves through your hips, knees, and feet, often well before the third trimester.

Changes in strength and movement tolerance. Abdominal and pelvic tissues change considerably throughout pregnancy. As the uterus grows, the abdominal muscles stretch and gradually provide less of the core support they normally lend to the spine, shifting more of the stabilising work onto the back and pelvis.

Common Pregnancy-Related Pain Patterns

Lower back pain is the most common complaint, usually related to the postural and load changes above.

Pregnancy-related pelvic girdle pain (PGP) can cause pain at the front or back of the pelvis and may also be felt around the hips or thighs. Symptoms are often aggravated by walking, stairs, standing on one leg, getting in and out of a car or turning over in bed. The older term “symphysis pubis dysfunction” or SPD is sometimes still used

Leg pain and nerve-related symptoms. Some pregnant people experience pain, tingling or numbness extending into the buttock or leg. These symptoms deserve proper assessment because they may arise from the lower back or other nerve-related causes rather than simply being assumed to result from the baby's position.

Round ligament pain — a sharp, brief pain low in the belly, often with sudden movement or position changes — is generally a normal part of pregnancy as ligaments stretch to support the growing uterus, though it's worth distinguishing from other pain patterns during an assessment.

When Pregnancy Pain Needs Immediate Medical Attention

Musculoskeletal discomfort is common during pregnancy, but new pain should not automatically be assumed to be coming from the back or pelvis. Certain symptoms require prompt assessment by your midwife, GP, obstetric team or hospital.

Contact your care provider immediately for:

• Vaginal bleeding or fluid leaking

• Severe or persistent headache, especially with vision changes or sudden swelling in the face or hands

• Decreased or absent fetal movement

• Regular contractions before 37 weeks

• Severe abdominal pain that feels different from typical round ligament discomfort

• Fever or chills

If something feels significantly different from your usual pregnancy symptoms, contact your maternity care provider.

Outside of these warning signs, the everyday back, hip, and pelvic discomfort many people experience during pregnancy is very responsive to appropriate, gentle care.

How Pregnancy-Safe Chiropractic Care Works

Care during pregnancy should be modified according to the stage of pregnancy, individual comfort, medical history and the specific musculoskeletal problem being treated. Adapted tables and supportive pillows that accommodate a growing belly, along with side-lying or other comfortable positions, and gentle techniques can support the increased joint laxity of pregnancy.

An assessment focuses on your movement, strength, and functional activities alongside a conversation about your specific symptoms, trimester and any risk factors as part of a broader care team, not in place of it.

Care commonly includes:

• Gentle, pregnancy-adapted adjustments to the pelvis and spine to support better alignment and comfort

• Soft tissue therapy for tight muscles in the lower back, hips, and upper back

• Exercise and rehabilitation to maintain or build appropriate strength and movement tolerance as pregnancy progresses.

• Practical advice around sleeping, walking, work, lifting and changing positions during daily life.

• Support belts where appropriate, particularly for some presentations of pelvic girdle pain.

The goal throughout is comfort, mobility, and supporting your body through the physical demands of pregnancy — always in coordination with your obstetric care.

Simple Things That Can Ease Pregnancy Aches

• Sleep on your side with a pillow between your knees and one supporting your belly

• Consider a supportive maternity belt if pelvic girdle pain is significant, particularly with walking

• Stay active where comfortable

• Choose supportive, low-heeled footwear as your balance and centre of gravity shift

• Be mindful of posture during long periods of sitting or standing, and change position regularly

• Modify aggravating activities, particularly for pelvic girdle pain

Common Pregnancy Pain Myths, Busted

"Back pain is just something you have to live with during pregnancy." It's common, but common doesn't mean untreatable. Many people find meaningful, lasting relief with the right combination of gentle care and adjustments to daily movement .

“Pregnancy means I can't receive any hands-on treatment.” Some forms of manual therapy can be modified to accommodate pregnancy, but whether a particular treatment is appropriate depends on your stage of pregnancy, symptoms, health history and individual circumstances. Treatment should never replace appropriate obstetric or maternity care.

"Any pain must mean something is wrong with the baby." Most musculoskeletal aches during pregnancy are related to the very normal hormonal, postural, and structural changes your body is going through, and aren't a reflection of your baby's wellbeing. However, because some pregnancy complications can also cause pain, new, severe or unusual symptoms — particularly when accompanied by bleeding, fluid loss, fever, reduced fetal movement or other warning signs — should be assessed promptly by your maternity care provider.

The Takeaway

Pregnancy places significant new demands on the body in a relatively short period of time. Back, hip and pelvic discomfort are common, but that doesn't mean every symptom should simply be accepted or pushed through.

If pain is making walking, sleeping, working or everyday movement more difficult, an assessment can help determine whether the problem appears musculoskeletal, identify practical ways to manage it and make sure there are no features that require further medical assessment.

Where appropriate, care may include movement strategies, exercise, rehabilitation and modified hands-on treatment — always alongside, rather than instead of, the care provided by your midwife, GP or obstetric team.
