How can round ligament pain during pregnancy be controlled?

Round Ligament Pain Control During Pregnancy

Round ligament pain should be managed primarily with activity modification, pelvic tilt exercises, and acetaminophen, reserving NSAIDs for short-term use only before 28 weeks gestation. 1, 2

Understanding the Condition

Round ligament pain results from hormonal-induced ligamentous laxity that reduces ligament stiffness and weakens joint stability, combined with biomechanical changes from increased abdominal mass and shifts in the center of gravity. 2 Postural adaptations as pregnancy progresses place additional stress on supporting structures. 2

First-Line Non-Pharmacological Management

Activity Modification:

• Avoid heavy lifting (10-20 kg or 22-44 lb) more than 20 times per week. 2
• Maintain regular moderate-intensity physical activity accumulated over at least 3 days per week. 2
• Combine aerobic exercise with resistance training, as this is more effective than aerobic exercise alone. 2
• Include yoga and gentle stretching for additional muscle spasm relief. 2

Pelvic Tilt Exercise:

• Pelvic (hip) tilt exercises are effective in reducing ligament pain intensity and duration. 3
• This exercise promotes patient comfort and facilitates self-care in relieving ligament pain during pregnancy. 3

Pharmacological Management

First-Line Medication:

• Acetaminophen (paracetamol) is the first-line medication due to its favorable safety profile throughout all trimesters. 1
• Dosing: 975 mg every 8 hours or 650 mg every 6 hours orally. 1
• Acetaminophen is considered the safest analgesic for mild to moderate pain at any stage of pregnancy. 1

Second-Line Options (Use with Caution):

• NSAIDs can be used ONLY before 28 weeks gestation for pain not controlled by acetaminophen. 1, 2
• Ibuprofen 600 mg every 6 hours by mouth can be considered. 1
• Avoid NSAIDs after 28 weeks gestation as they can cause premature closure of the fetal ductus arteriosus and oligohydramnios. 1

Severe Pain:

• Severe musculoskeletal pain after vaginal delivery is unusual and should prompt evaluation for unrecognized complications (such as round ligament varicocele). 1, 4, 5, 6
• If opioids are absolutely necessary for severe pain unmanaged by nonopioid options, use the lowest effective dose for the shortest time possible, with morphine as the preferred agent. 1

Red Flags Requiring Urgent Evaluation

Stop activity and seek immediate medical attention if experiencing:

• Persistent excessive shortness of breath. 2
• Severe chest pain. 2
• Regular and painful uterine contractions. 2
• Vaginal bleeding. 2
• Persistent loss of fluid from the vagina. 2
• Persistent dizziness or faintness. 2

Common Pitfalls to Avoid

• Underreporting by patients is common—active questioning is required to identify round ligament pain. 2
• Inadequate activity modification, such as failing to adjust heavy lifting and physical workload, can worsen symptoms. 2
• Severe musculoskeletal pain is associated with sleep disturbances, altered daily activities, and depression, highlighting the importance of considering psychosocial factors. 2
• Avoid muscle relaxants like atracurium and mivacurium during pregnancy when possible. 2

Prognosis and Follow-Up

• For most women, round ligament pain resolves spontaneously after delivery. 2
• Women at highest risk for persistent postpartum pain include those with back pain prior to pregnancy, early symptom onset, higher pain severity, or both low back pain and pelvic girdle pain simultaneously. 2

Special Consideration: Round Ligament Varicocele

Round ligament varicocele is a rare condition that presents as a unilateral or bilateral painful or painless inguinal mass during pregnancy. 4, 5, 6 It can clinically resemble an inguinal hernia on physical examination. 4, 5 Ultrasound with Doppler is the diagnostic imaging procedure of choice to differentiate this from inguinal hernia and prevent unnecessary surgical exploration. 5, 6 This condition is managed conservatively and typically regresses spontaneously postpartum. 6
