Round Ligament Pain: Causes, Symptoms & Relief
Understanding round ligament pain during pregnancy: symptoms, causes, and effective relief strategies.

What Is Round Ligament Pain?
Round ligament pain is a common discomfort experienced by many pregnant individuals, especially during the second trimester. This pain arises from the stretching and tightening of the round ligaments, which support the uterus as it grows to accommodate the developing baby. While round ligament pain is usually harmless, it can be startling and uncomfortable, especially when it occurs suddenly.
Symptoms of Round Ligament Pain
Round ligament pain typically presents as sharp, stabbing, or aching sensations in the lower abdomen, hips, or groin area. The pain may be felt on one side or both sides, though it is more commonly reported on the right side. Symptoms can include:
- Sharp, sudden pain in the lower belly, hips, or groin
- Aching or cramping feeling
- Pulling or stretching sensations
- Spasms or twinges in the lower abdomen
- Increased discomfort with sudden movements, such as standing up quickly, rolling over in bed, sneezing, coughing, or laughing
The pain is usually brief, lasting only a few seconds to a few minutes, but in some cases, it can persist for several hours. The intensity of the pain can vary from mild to severe, and it may be accompanied by a feeling of pressure or heaviness in the pelvic area.
Causes of Round Ligament Pain
Round ligament pain is caused by the stretching and tightening of the round ligaments as the uterus expands during pregnancy. The round ligaments are two cord-like structures that extend from the front of the uterus to the groin area. As the uterus grows, these ligaments must stretch to support the increasing weight and size of the uterus. This stretching can cause the ligaments to spasm or twitch, leading to pain.
Several factors can trigger or worsen round ligament pain:
- Sudden movements, such as standing up quickly or rolling over in bed
- Increased abdominal pressure from sneezing, coughing, or laughing
- Standing for long periods of time
- Physical activity or exercise
It is important to note that round ligament pain is different from pelvic girdle pain (also known as symphysis pubis dysfunction). While both types of pain occur due to changes in the body during pregnancy, round ligament pain is caused by the stretching of the round ligaments, whereas pelvic girdle pain is caused by the relaxation of the pelvic ligaments, leading to increased movement in the pelvic joints.
When Does Round Ligament Pain Occur?
Round ligament pain is most commonly experienced during the second trimester of pregnancy, typically between weeks 14 and 20. However, some individuals may begin to feel this pain earlier in pregnancy, and others may continue to experience it into the third trimester. The pain is usually more noticeable as the uterus grows and the round ligaments are stretched further.
How Is Round Ligament Pain Treated?
Round ligament pain is usually mild and can be managed with simple self-care measures. The following strategies can help relieve discomfort:
- Rest: Lying on your side with a pillow between your knees can help reduce pressure on the round ligaments.
- Apply warmth: Placing a warm compress on the lower abdominal area or taking a warm bath can help soothe the pain.
- Take pain relievers: Most people can safely take paracetamol (acetaminophen) during pregnancy, but it is important to check with your healthcare provider before taking any medication.
- Wear a belly band: An elastic belly band can provide extra support to your growing belly and help relieve pressure on the round ligaments.
- Stretch gently: Daily gentle stretches, such as bending and flexing your hip joint, can help relieve tension in the ligaments. Prenatal yoga and pelvic tilts are also beneficial.
- Move slowly: Avoid sudden movements and take your time when changing positions, such as getting up from sitting or lying down.
- Modify activity level: If certain activities trigger your pain, try to avoid them and take breaks throughout the day to rest.
When to Seek Medical Attention
While round ligament pain is usually harmless, there are certain symptoms that may indicate a more serious condition and require medical attention. Contact your healthcare provider if you experience any of the following:
- Intense or constant pain
- Fever or chills
- Bleeding
- Painful urination
- Unusual vaginal discharge
- Lightheadedness or dizziness
- Contractions (Braxton Hicks contractions are normal, but if you are unsure, consult your provider)
- Decreased fetal movement
If your pain does not improve with rest or becomes severe, it is important to seek medical advice to rule out other potential causes of abdominal pain during pregnancy.
Round Ligament Pain vs. Other Pregnancy Pains
It is important to differentiate round ligament pain from other types of pregnancy-related discomfort. The table below outlines the key differences:
| Pain Type | Location | Characteristics | Triggers |
|---|---|---|---|
| Round Ligament Pain | Lower abdomen, hips, groin | Sharp, stabbing, aching, pulling | Sudden movements, physical activity |
| Pelvic Girdle Pain | Pelvis, lower back, upper thighs, perineum | Dull, aching, radiating | Walking, standing, climbing stairs |
| Braxton Hicks Contractions | Uterus | Intermittent, tightening | Dehydration, physical activity |
Prevention Tips for Round Ligament Pain
While it may not be possible to completely prevent round ligament pain, there are steps you can take to reduce the likelihood and severity of discomfort:
- Avoid sudden movements and change positions slowly.
- Stay active with gentle exercises, such as walking, swimming, or prenatal yoga.
- Use a belly band for additional support.
- Rest frequently and avoid standing for long periods.
- Stay hydrated and maintain a healthy diet.
