Pregnancy Back Pain Relief: Causes, Exercises and Red Flags

Back pain affects most women at some point in pregnancy, and it usually gets more noticeable from the second trimester as your bump grows. The most effective pregnancy back pain relief combines good posture, regular gentle exercise, sleeping on your side with pillows for support, heat or a warm shower, and, if needed, a maternity support belt or a few sessions with a women’s health physiotherapist.

Back pain is common, but it is not something you simply have to put up with. And a few types of back pain are warning signs rather than ordinary aches. This guide explains both.

Why your back hurts in pregnancy

Several changes happen at once, and they add up:

• Hormones. Relaxin and other pregnancy hormones loosen the ligaments around your pelvis to prepare for birth, which makes the joints less stable.
• A shifting centre of gravity. As your bump grows, your weight moves forward and the curve in your lower back deepens.
• Stretched tummy muscles. Your abdominal muscles stretch and separate a little, so they support your spine less.
• Weight gain and fatigue, which put more load on tired muscles.
• Stress and poor sleep, which can make muscles tense and pain feel worse.

What to expect trimester by trimester

Pelvic girdle pain and sciatica

Pelvic girdle pain (PGP), sometimes called symphysis pubis dysfunction or SPD, is pain at the front of the pelvis, around the hips or at the back near the dimples of your lower back. It is often worse when turning in bed, climbing stairs, getting in or out of a car, or standing on one leg. Sciatica-type pain shoots down the buttock and back of one leg. Both are common and treatable, so mention them to your doctor, who can refer you to physiotherapy.

Posture and everyday habits

Small changes to how you sit, stand and move make a real difference over a day.

• Stand tall. Imagine a string pulling the top of your head up; tuck your tailbone gently under and keep your shoulders relaxed.
• If you stand a lot, rest one foot on a low stool or step and switch sides regularly.
• Sit well supported in a chair with a back, with a small cushion behind your lower back and your feet flat on the floor. Get up and move every 30 to 45 minutes if you work at a desk.
• Lift with your legs, not your back: bend your knees, keep the load close, and do not twist. Let someone else carry the heavy grocery bags or lift your toddler into the car where possible.
• Keep knees together when getting in and out of a car or bed, which helps if you have pelvic pain.
• Wear low, supportive shoes. Flat slippers with no arch support and high heels can both make things worse.

Gentle exercises that help

Staying active is one of the best treatments for pregnancy back pain. If your pregnancy is uncomplicated and your doctor is happy, try these a few times a week. Stop if anything causes sharp pain.

• Pelvic tilts. On hands and knees, or standing with your back against a wall, gently tilt your pelvis to flatten your lower back, hold for a few seconds, then release. Repeat about 10 times.
• Cat-cow. On hands and knees, slowly round your back up towards the ceiling, then let it return to neutral. Move with your breath.
• Child’s pose, knees wide. Sit back towards your heels with your knees apart to make room for your bump, arms stretched forward, and breathe slowly.
• Pelvic floor and deep tummy muscle work. Gently draw in your pelvic floor and lower tummy together, hold, then release. These muscles support your spine and pelvis.
• Swimming and water exercise. The water takes the weight off your joints, and a pool is a welcome escape from Singapore’s heat.
• Walking, in shorter, more frequent sessions if longer walks set off pelvic pain.

Our guide to exercise during pregnancy explains how much activity is recommended and which prenatal classes to look for.

Support belts, heat and other relief

Maternity support belts

A maternity belt or bump band sits under your bump and around your lower back to share some of the load. Many mums find it helpful in the third trimester, for long periods on their feet, or with pelvic girdle pain. Use it for a few hours at a time rather than all day, so your own muscles keep working, and ask a physiotherapist about fit if you have pelvic pain.

Heat, massage and pain relief

• A warm (not hot) shower or a warm compress on your lower back can relax tight muscles. Avoid lying on a heat pad on your tummy.
• Prenatal massage from a therapist trained in pregnancy massage can help. Tell them how many weeks pregnant you are.
• Paracetamol is generally considered the first choice for pain relief in pregnancy. Follow the label or your doctor’s advice. Avoid anti-inflammatory painkillers such as ibuprofen unless your doctor says otherwise, particularly in later pregnancy.
• Check with your doctor before using medicated plasters, rubs or traditional oils, as some contain ingredients not recommended in pregnancy.

Sleeping comfortably

Side sleeping is recommended from the third trimester, and many mums find it the most comfortable position well before then. For less back strain:

• Lie on your side with your knees and hips bent, and a pillow between your knees and ankles to keep your hips level.
• Tuck a small pillow or rolled towel under your bump, and another behind your back.
• To turn over, keep your knees together and roll your whole body as one unit.
• To get out of bed, roll onto your side, drop your legs over the edge and push yourself up with your arms.

A full-length or U-shaped pregnancy pillow does all of this in one; see our round-up of the best maternity pillows in Singapore. A mattress that is too soft can also make back pain worse. If heartburn is what keeps you awake, see our guide to heartburn relief in pregnancy. If a stuffy nose is the culprit, see our guide to pregnancy congestion and nosebleeds.

Physiotherapy in Singapore

If pain is stopping you from working, walking or sleeping, ask your gynae or polyclinic for a referral to a women’s health physiotherapist. Public hospitals with maternity services, including KKH, NUH and SGH, have physiotherapy teams who see pregnant patients, and there are also private physiotherapy clinics with women’s health specialists. Subsidised rates generally need a referral from your doctor; ask the clinic for current fees before you book.

A physiotherapist can assess your back and pelvis, give you exercises tailored to your pain, advise on support belts or crutches if needed, and show you positions for labour that go easy on your back. KKH’s page on coping with common pregnancy symptoms has more general advice.

Red flags: back pain that needs a doctor

Pain high in your upper back or under the ribs on the right side, especially with a headache, blurred vision or swelling, can also be a sign of pre-eclampsia in later pregnancy. Our third trimester guide covers these warning signs in more detail.

The bottom line

Most pregnancy back pain comes from hormones loosening your joints and a growing bump changing your posture. Keep moving with gentle exercise and swimming, pay attention to how you sit, lift and sleep, use a support belt for heavier days, and ask for a physiotherapy referral if pain is limiting your life. Never ignore back pain that comes in waves, comes with fever or bleeding, or affects your bladder or legs.
