What Is Spd During Pregnancy? Simplified

If you feel a sharp, burning pain right at the front of your pelvis — often when you lift a leg, turn over in bed, or walk up stairs — you may be feeling symphysis pubis dysfunction. SPD during pregnancy is pain that comes from the joint where the two halves of your pelvis meet at the front. That joint is called the symphysis pubis. In pregnancy, hormones soften the ligaments that hold it together, and for some women the joint becomes unstable enough to cause real pain.

SPD is sometimes called pelvic girdle pain, or PGP. The two terms overlap, and different clinicians use them differently. SPD is not dangerous to your baby. It is not a sign that something is wrong with the pregnancy. It is a mechanical problem in your own pelvis, and it is common.

What Is SPD During Pregnancy?

SPD is pain and instability in the symphysis pubis joint during pregnancy. The joint sits at the very front of the pelvis, below the pubic hairline. It is a cartilaginous joint, meaning the two pubic bones are connected by a disc of cartilage rather than a fluid-filled capsule like your knee.

In a non-pregnant pelvis, that joint moves very little. During pregnancy, the hormone relaxin and other hormonal changes soften the ligaments throughout the pelvis. This loosening is normal and helps the pelvis widen for childbirth. In SPD, the softening goes further than the body can comfortably manage, and the joint becomes hypermobile — it moves more than it should.

The result is pain, usually felt as a sharp or burning sensation directly over the joint. Some women describe it as a feeling that the pelvis is grating or slipping. The pain often radiates into the groin, the inner thighs, or the lower back.

One clarification worth making: SPD is not the same as the general lower back pain many pregnant women get. It has a specific location and specific triggers. That distinction matters because the two problems are managed differently.

What Does SPD Pain Actually Feel Like?

The pain of SPD is usually sharp and localized. Most women point to one spot at the front of the pelvis. The pain tends to be worse with movement that puts uneven load on the two sides of the pelvis.

Common triggers include:

• Walking, especially with long strides
• Climbing stairs, particularly one step at a time
• Turning over in bed
• Getting in and out of a car
• Standing on one leg, such as when dressing
• Lifting a leg to put on shoes or pants
• Separating your legs, such as getting out of a bathtub

Some women also feel or hear a clicking or grinding sensation at the joint when they move. The pain can range from mild discomfort to pain that makes walking difficult. It can also spread to the lower back, hips, or perineum.

What makes SPD distinctive is that a single leg movement often provokes it. That is because moving one leg while the other stays planted puts a shearing force across the front joint.

Who Gets SPD and When Does It Start?

SPD most often appears in the second half of pregnancy, but it can begin as early as the first trimester. Some women notice it for the first time after a previous pregnancy, a fall, or an episode of heavy lifting.

Several factors are associated with a higher chance of developing it. These include:

• Previous pelvic injury or pelvic surgery
• A history of low back pain
• Carrying a larger baby or twins
• Being physically active in a way that loads the pelvis unevenly
• Previous pregnancy with SPD

Having one or more of these factors does not mean you will develop SPD. Many women with none of them still get it, and many with several never do. The exact reason some women develop it and others do not is not fully understood.

How Is SPD Diagnosed?

SPD is diagnosed mainly by history and physical examination. There is no blood test or scan that confirms it. Imaging is usually not needed.

A clinician will ask where the pain is, what makes it worse, and when it started. They may then perform simple movement tests, such as asking you to lie on your back and move one leg, or to press on the front joint to see if it is tender.

The key diagnostic feature is pain localized to the symphysis pubis that is reproduced by specific movements. If pain is felt mainly in the lower back or buttock, the diagnosis may be different, and the treatment approach changes.

Some clinicians use the term pelvic girdle pain to cover pain from the front joint, the back joints of the pelvis, or both. Others reserve SPD specifically for the front joint. This is a naming difference, not a difference in what is happening in your body.

What Helps With SPD Pain?

Most SPD improves with a combination of activity changes, physical therapy, and support. The goal is to reduce the load on the front joint and strengthen the muscles that help stabilize the pelvis.

Physical therapy is the mainstay of treatment. A pelvic health physiotherapist can teach you exercises to strengthen the deep abdominal and pelvic floor muscles, which help support the pelvis. They can also advise on posture and movement strategies that avoid provoking the pain.

A pelvic support belt can help some women. These belts wrap around the hips and provide external compression that reduces movement at the front joint. Evidence for how well they work varies, and they help some women more than others. A physiotherapist can advise on correct fitting and use.

Activity modification is often the most effective single step. This means avoiding the movements that hurt most. Practical adjustments include:

• Keeping your knees together when turning in bed
• Sitting down to get dressed rather than standing on one leg
• Taking stairs one step at a time, leading with the less painful leg going up
• Avoiding standing on one leg for long periods
• Using a pillow between your knees when sleeping on your side

Pain relief during pregnancy should always be discussed with your clinician. Paracetamol (acetaminophen) is generally considered the first-line option for pain in pregnancy, but you should confirm with your own doctor or midwife what is appropriate for you. Do not start or stop any medication during pregnancy without medical advice.

Some women are offered crutches to reduce weight-bearing through the pelvis. This is a clinical decision made case by case.

Will SPD Affect My Labor and Delivery?

SPD does not usually prevent a vaginal birth. Many women with SPD deliver vaginally without problems related to the joint.

That said, the position you use for pushing and birth can affect how much strain the front joint feels. Some women find certain positions more comfortable than others. Lying on your back with legs widely separated, or using stirrups, can put more load on the joint. Kneeling, side-lying, or using a birth stool may be more comfortable for some women.

It is worth telling your midwife or obstetrician about your SPD before labor. They can help you plan positions that reduce strain. In some cases, an anesthesiologist may be involved in planning pain relief, and a physiotherapist can advise on positions.

For the small number of women with severe SPD, the option of a cesarean delivery may be discussed. This is not routine, and the decision depends on how much the joint is affected and how you are managing. It is a conversation to have with your clinical team, not a decision to make on your own.

Does SPD Go Away After Birth?

For most women, SPD improves significantly in the weeks after delivery. The hormonal changes that softened the ligaments settle, and the joint gradually regains stability.

Recovery time varies. Some women feel better within days. Others take weeks or a few months. A smaller number continue to have some pain beyond that, particularly if the joint was significantly affected or if there was pre-existing pelvic instability.

If pain persists after birth, it is worth seeing a pelvic health physiotherapist. They can assess whether the joint is still unstable and provide a rehabilitation program. Continuing to avoid the movements that provoke pain, and gradually building strength, is generally the approach.

A note about future pregnancies: women who have had SPD in one pregnancy are more likely to have it again in a later one. That does not mean it will be as severe. Early physiotherapy in a subsequent pregnancy may help.

What SPD Is Not

SPD is not a sign that your baby is in danger. It is not a disease. It is a mechanical problem in your own pelvis, and it is treatable.

It is also not the same as the “lightning crotch” some women feel — brief, sharp shooting pains in the vagina or rectum that come and go quickly. That is usually related to nerve pressure and is different from the persistent, movement-related pain of SPD.

And it is not something you should simply push through. Continuing to do activities that provoke sharp pain can make the joint more irritated. Rest and modification are not signs of weakness. They are part of managing the problem.
