Quick answer

What is Round ligament pain?

Round ligament pain is a common and usually harmless type of pain in pregnancy, felt low down in the tummy or groin, on one or both sides. It is caused by stretching and thickening of the round ligaments — the bands of tissue that help support the womb (uterus) within the pelvis.

  • How it is treated: Round ligament pain does not usually need any specific treatment, as it is a normal consequence of the growing womb and tends to settle by itself.
  • Self-care: Moving slowly and gently when changing position, supporting the bump when coughing or sneezing, resting or changing position when pain comes on, and warmth for comfort all ease round ligament pain, which is a normal, brief part of pregnancy.
  • When to seek help: Contact a midwife or GP (or maternity unit) if pregnancy tummy pain is severe, constant, one-sided and persistent, or comes with bleeding, a high temperature, pain or burning on passing urine, regular tightening or contractions, reduced baby movements, or feeling unwell — these need assessment, as they may not be round ligament pain.

What it is

Round ligament pain is a common and usually harmless type of pain in pregnancy, felt low down in the tummy or groin, on one or both sides. It is caused by stretching and thickening of the round ligaments — the bands of tissue that help support the womb (uterus) within the pelvis. As the womb grows during pregnancy, particularly in the second trimester, these ligaments stretch and thicken, and sudden movements can pull on them and cause a brief, sharp, stabbing or pulling pain, or a duller ache. It is typically triggered by movements such as standing up quickly, rolling over in bed, coughing, sneezing, or laughing, and it often eases quickly when you stop moving or change position. The pain is usually short-lived (lasting seconds to minutes) and is felt low in the bump or groin, rather than higher up. Round ligament pain is a normal part of many pregnancies and is not harmful to the baby. However, because tummy pain in pregnancy can occasionally have other causes — some of which need urgent attention — it is important to recognise the difference: pain that is severe, constant, one-sided and persistent, or accompanied by other symptoms (such as bleeding, a high temperature, pain on passing urine, regular tightening, or feeling unwell) should always be checked.

How it is treated

Round ligament pain does not usually need any specific treatment, as it is a normal consequence of the growing womb and tends to settle by itself. Simple measures can reduce it and ease discomfort: moving more slowly and gently, particularly when changing position, standing up, or getting out of bed; bending and supporting the bump when you feel a cough or sneeze coming; changing position or resting when the pain comes on; and a warm (not hot) bath or a warm compress for comfort. Supporting the bump — for example with a pillow when lying down, or with maternity support wear — can help some women. The pain typically eases as you rest or change position, and often becomes less of a problem later in pregnancy. The most important part of managing round ligament pain is being able to distinguish it from pain that needs medical attention: because it is brief, movement-related, and low down, it is usually reassuringly recognisable, but any tummy pain in pregnancy that is severe, persistent, constant, or comes with warning signs should be checked promptly by a midwife or GP. The reassuring message is that round ligament pain is common, harmless, and part of normal pregnancy, and that it is usually brief and eased by moving slowly and gently — while any concerning or persistent pain should always be assessed.
