Pregnancy and postpartum back and pelvic pain: what it is and how care can help

You are not imagining it, and you are not alone

If your lower back has started aching by mid-afternoon, or a deep, grinding pain has settled over your pubic bone and hips, or getting out of the car has become something you have to plan for — this is one of the most common experiences of pregnancy. It can be exhausting, and it can be frightening the first time it flares. It can also feel oddly invisible: the kind of pain that is hard to explain to people who assume a little back discomfort is just part of being pregnant.

Here is a reassuring place to begin. For most people, this kind of pain is common, it is not a sign that something is wrong with the baby, and it usually improves a great deal after birth. That does not make it trivial while you are living with it. This guide explains what back and pelvic-girdle pain in pregnancy actually are, the warning signs that mean you should be checked promptly, how physiotherapists and your maternity team can help, and what you can do day to day — always alongside, never instead of, the people looking after your pregnancy.

Two related problems: low-back pain and pelvic-girdle pain

Two overlapping things are usually going on, and it helps to tell them apart.

Low-back pain in pregnancy is felt in the lower back, much like the back pain many people know from other times in life. Pelvic-girdle pain (PGP) is different: it is pain in the joints of the pelvic ring — over the pubic bone at the front (sometimes called symphysis pubis dysfunction), across one or both sides of the lower back near the dimples above the buttocks (the sacroiliac joints), or a mix of these — and it can spread into the buttocks or the back of the thigh [1][2]. European clinical guidelines describe PGP as pain felt between the top of the back of the pelvis and the crease of the buttock, often near the sacroiliac joints, sometimes with pain at the pubic joint, and note that a hallmark is reduced endurance for standing, walking, and sitting [2]. These guidelines treat PGP as a distinct problem from ordinary low-back pain — related, able to happen together, but worth recognising in its own right so the right kind of help can be offered [2][3].

Why does it happen? Pregnancy changes the body in ways that load these joints and muscles differently. The growing uterus shifts your centre of gravity and the curve of your spine, and hormonal changes affect the ligaments that support the pelvis, so the joints move and load in new ways. Reviews of PGP describe it as a musculoskeletal pain of the pelvic ring rather than damage to the baby or a sign of the pelvis "coming apart" [3]. The strongest risk factors identified in careful studies are a history of previous low-back or pelvic pain, previous pelvic injury, and physically strenuous work — while some things people worry about, such as maternal age or the baby's weight, have not been reliably linked to it [3].

It is common. Depending on how it is defined and measured, pelvic-girdle pain affects roughly 1 in 5 pregnant people, and by some estimates a good deal more [1][3]. So if you have it, you are in very large company.

Red flags: when to seek prompt or urgent help

Most pregnancy-related back and pelvic pain is musculoskeletal and not dangerous. But some symptoms need timely assessment, because a few serious problems can first show up as back or pelvic-area pain. Think of the list below as prompts to get checked — not a way to diagnose yourself.

Seek urgent, same-day medical care (go to an emergency department or call your local urgent line) if you have any of these, which can point to pressure on the nerves at the base of the spine (a rare condition called cauda equina syndrome) [7]:

• New difficulty passing urine, loss of the sensation of needing to go, or leaking without realising it.
• New loss of control of your bowels, or numbness when you wipe after using the toilet.
• Numbness or pins-and-needles around your genitals, inner thighs, or back passage (sometimes called "saddle" numbness).
• New weakness, numbness, or heaviness in one or both legs.

These are medical emergencies at any stage of pregnancy, and timing matters, so do not wait to see whether they pass [7].

Contact your midwife, obstetrician, or family doctor promptly (rather than waiting) if:

• Your pain is severe, came on suddenly, or is much worse on one side.
• The pain is stopping you from walking, turning in bed, or managing day to day [1].
• You have a fever, feel generally unwell, or have pain with vaginal bleeding or a change in your baby's movements — these need assessment by your maternity team, not a physiotherapist.
• You have calf pain or swelling in one leg, which needs to be checked because it can signal a blood clot.

Your maternity care team — midwife and obstetrician — are the right people to sort out which pains are the ordinary aches of pregnancy and which need a closer look. When in doubt, it is always reasonable to ask them.

How care can help

There is no single "best" treatment, and honest sources are clear that the effects of most approaches are modest and the research is mixed. What follows is an honest look at what different kinds of help offer and what the evidence does and does not show — so you can have an informed conversation, not so any one path can be sold to you.

Physiotherapy

Physiotherapists — especially those with training in pregnancy-related pelvic and back pain — usually start by assessing how your back, pelvis, and hips move and load, then build an individual program. This commonly includes specific exercises to support the muscles around the trunk and pelvis, advice on movement and posture, and hands-on techniques, sometimes with a support belt or, in more limited cases, crutches to help you get around [1][6].

What does the evidence say? A large Cochrane systematic review — a careful pooling of many trials — found low-quality evidence that exercise (on land or in water) may reduce pregnancy-related low-back pain, and moderate-to-low-quality evidence that exercise improves day-to-day function and reduces sick leave compared with usual prenatal care [4]. For combined low-back and pelvic pain, they found moderate-quality evidence that an eight-to-twelve-week exercise program reduced the number of people reporting pain [4]. A separate 2023 review that pooled 12 trials found exercise produced lower pain scores than usual care (a moderate effect), but the result did not reach statistical significance and the studies varied widely — and, importantly, exercise did not appear to prevent the pain from starting in the first place [5]. The honest summary: exercise and physiotherapy are reasonable, low-risk options that help many people manage the pain and stay functional, rather than a guaranteed fix or a way to prevent it [4][5].

Reviews also suggest that individually tailored, supervised physiotherapy tends to be more helpful than generic back-and-pelvis exercises given to everyone [3] — which is part of why a personalised assessment is worth having.

Pelvic-floor physiotherapy

Pelvic-floor physiotherapy is a specialised area focused on the muscles that support the pelvis, bladder, and bowel. During and after pregnancy, these muscles are under new demands, and pelvic-floor physiotherapists offer assessment and guided training (often called pelvic-floor muscle training) alongside the broader work above.

The evidence here is clearest for a related problem — bladder leakage — rather than for pain itself. A Cochrane review found that pelvic-floor muscle training taught by a professional to women in their first pregnancy probably reduces the risk of urinary leakage in late pregnancy and after birth, though the picture for treating leakage that has already started, and for longer-term results, is less certain [6]. Because pelvic-floor, bladder, and pelvic-girdle problems often travel together after birth, a pelvic-floor physiotherapist can be a useful part of the team; the strength of the evidence varies by the specific problem being addressed [6].

Your maternity and obstetric team

Your midwife and obstetrician are central, not a fallback. They can confirm that what you are feeling is the common musculoskeletal pain of pregnancy rather than something that needs different attention, arrange a referral to a physiotherapy service that specialises in pregnancy-related pelvic joint problems, and advise on comfort measures and pain relief that are appropriate for your stage of pregnancy [1][3]. Pain-relief choices in pregnancy are genuinely different from other times of life — some medicines are limited or best avoided at certain stages — which is exactly why these decisions belong with the professionals looking after your pregnancy rather than with a general article or an over-the-counter guess [3].

Self-management, and what to expect after birth

Alongside professional care, a lot of the day-to-day management is in your hands. The steps below reflect the general direction of the patient guidance and reviews above, and are gentle and low-risk for most people — though it is always worth checking them with your own physiotherapist or maternity provider:

• Keep moving within comfortable limits. Staying gently active is generally encouraged; the aim is to avoid the specific movements that sharply aggravate your pain rather than to stop moving altogether [1].
• Work with, not against, the painful joints. Many people find it easier to keep the knees together when turning in bed or getting in and out of a car, to take stairs one step at a time, and to sit down to dress. Balancing weight evenly — avoiding standing on one leg to pull on trousers, for example — can ease the pubic joint [1].
• Consider a pelvic support belt. Physiotherapists sometimes recommend a support belt to help ease pain and make moving around easier; it is a commonly offered, low-risk option, though the evidence behind it is limited [1][3].
• Rest and comfort measures. Pillows to support your bump and between your knees at night, supportive shoes, warm baths, and pacing your day to avoid long stretches of standing or walking are widely suggested and simple to try [1].
• Ask about pain relief and aids. If pain is significant, ask your maternity team about pregnancy-appropriate pain relief, and your physiotherapist about aids like a belt or crutches [1][3].

And here is the part worth holding onto: the outlook after birth is generally good. Patient information from maternity services notes that pelvic-girdle pain often does not fully settle until after the baby is born, and that it is not harmful to your baby [1]. Reviews back this up — in one summary of the evidence, symptoms had resolved in roughly 9 in 10 people within about three months of delivery, with only a small minority reporting ongoing pain a year later [3]. That is genuinely encouraging. It is also honest to say that "most" is not "everyone": a minority do have pain that lingers, and it can return in a future pregnancy, sometimes more strongly [3]. If your pain is not improving in the weeks after birth, that is a reason to be reassessed rather than to assume you simply have to live with it.

Getting the right help

Pregnancy-related back and pelvic-girdle pain is common, usually not a sign of danger, and for most people it eases considerably after birth. But "usually" is not "always," and your body and your pregnancy are specific to you. No article can examine you, feel how your pelvis is moving, weigh your particular history, or tell you which combination of exercise, hands-on care, support, and pain relief fits your situation — or spot the occasional warning sign that needs a different kind of attention.

That is exactly what your care team is for. A physiotherapist, ideally one experienced in pregnancy-related pelvic and back pain, can assess how your back and pelvis are working and build a plan suited to you and your goals. Your midwife and obstetrician can confirm what is going on, rule out the warning signs above, and coordinate care and pain relief that are safe for your stage of pregnancy. If one reasonable approach is not helping after a fair try, that is a reason to go back and adjust the plan together — not to give up, and not to push through pain alone. Reach out early, ask questions freely, and let the people looking after you help you carry this part.
