If you're in your second trimester and have experienced a sudden, sharp, stabbing or cramping pain in your lower abdomen, groin, or hip that comes on quickly when you change positions, cough, sneeze, or roll over in bed, you've likely had your first encounter with round ligament pain. It's one of the most startling sensations in pregnancy, and for good reason: it can feel severe enough to take your breath away in the moment. For expectant mothers across Atlanta, Charlotte, Greenville, Knoxville, and Beaufort, round ligament pain is one of the most common complaints we address at Prenatal Chiropractic Southeast.
What the Round Ligament Is and Why It Hurts
The round ligaments are a pair of cord-like structures that run from the front of the uterus, through the inguinal canal, and attach to the labia majora. Their job is to support the uterus and help maintain its position as the body changes. Under normal circumstances, you'd never think about them.
During pregnancy, the uterus grows dramatically. By the second trimester, it has expanded significantly from its pre-pregnancy size, and it continues to grow through the end of the third trimester. As the uterus enlarges, the round ligaments are pulled, stretched, and placed under a level of tension they're not accustomed to handling. They become thickened, elongated, and hyperaware of sudden movements.
The pain itself occurs when these already-taut ligaments are suddenly stretched further. Any quick movement that shifts the position of the uterus, whether rolling over in bed, standing up quickly, a sudden laugh, or a sneeze, can trigger an acute spasm in the round ligament. The pain typically lasts a few seconds to a couple of minutes and then fades. If it persists longer or is accompanied by fever, bleeding, or significant abdominal cramping, that warrants evaluation by your OB.
Why Some Pregnant Women Get It More Than Others
Round ligament pain varies significantly in severity and frequency between individuals, and there are structural reasons why. Pelvic alignment plays a central role. When the pelvis is level and symmetrical, the uterus sits in a balanced position and the round ligaments are under equal tension on both sides. When the pelvis is tilted, rotated, or asymmetrically positioned, the uterus shifts with it, placing unequal tension on the round ligaments. The side under greater tension becomes more susceptible to painful spasms.
Sacroiliac joint dysfunction, which is common during pregnancy due to the effects of the hormone relaxin on ligament laxity, is a frequent contributor to pelvic asymmetry. When the sacroiliac joints move unevenly, the pelvis can lock in a rotated position, directly affecting the tension placed on the round ligaments. This is one of the key reasons why chiropractic care, specifically the Webster Technique, can significantly reduce round ligament pain.
Common Round Ligament Pain Triggers
- • Rolling over in bed, especially quickly
- • Standing up from a seated or lying position
- • Sneezing, coughing, or laughing
- • Climbing stairs or stepping up
- • Prolonged walking, especially on uneven terrain
- • Sudden twisting motions of the torso
The Webster Technique and Pelvic Balance
The Webster Technique is a specific chiropractic analysis and adjustment protocol designed for pregnant women. It focuses on assessing and correcting sacral misalignment and sacroiliac joint dysfunction, and it also addresses the soft tissue elements that are secondary to pelvic imbalance, including the intrauterine constraint that round ligament tension creates.
When the sacrum is adjusted and the pelvis achieves better symmetry, the uterus is better supported in a balanced position. This directly reduces the unequal tension on the round ligaments, decreasing the frequency and intensity of the painful spasms. Many patients report significant reduction in round ligament pain within their first few weeks of Webster Technique care. As the pregnancy progresses and the uterus continues to grow, ongoing care helps maintain pelvic balance so the ligaments are not subjected to disproportionate strain.
Webster Technique care is gentle, safe, and appropriate throughout all three trimesters. All of our clinicians who provide prenatal care are Webster Technique certified. The adjustment itself is adapted for pregnancy, using modified positioning and lighter contacts that are comfortable for the mother and safe for the baby.
What Patients Can Do Between Visits
In addition to Webster Technique adjustments, a few practical modifications help manage round ligament pain between visits. Moving slowly and intentionally when changing positions gives the ligaments time to adapt to the shift in uterine position. When you need to cough, sneeze, or laugh, bending slightly at the hip can reduce the sudden tension spike. A supportive maternity belt can provide additional mechanical support for the uterus, reducing some of the load on the round ligaments during activity.
Warm compresses applied to the lower abdomen can help relax the round ligament spasm after it occurs. Side-lying with a pregnancy pillow that supports the belly reduces the overnight tension on the ligaments in the hours when you're not moving.
