Why Round Ligament Pain Happens on One Side More During Pregnancy

When you conceive, you might encounter more aches or pains as your body changes. One common issue you may face is round ligament pain, which can be a surprise because it often feels stronger on one side of your belly. It’s usually nothing to worry about, but it can still give you trouble if you’re not sure what’s going on. This article explains why round ligament pain tends to happen more on one side, what it feels like, and how to safely manage it.

Pregnancy brings changes in your body, and that can cause some strange feelings that you might not have encountered before. One such sensation is round ligament pain, which occurs when you move and feels like a quick, intense discomfort or a tug. It might worry you that this pain happens on just one side, not both.
Understanding the reason behind this can help reduce stress and reassure you that, in most cases, this pain is just part of your pregnancy.

What Is Round Ligament Pain?

Round ligament pain is a common discomfort during pregnancy that affects the lower abdomen or groin. Before pregnancy, the round ligaments, which are rope-like tissues, support your uterus. They’re usually firm but bendable. As the uterus grows during pregnancy, these ligaments stretch and become thicker to support the additional weight.
This stretching might lead to pain, particularly in the second trimester, although some expectant mothers feel it earlier or later.
What Is the Location of the Round Ligaments?
You have two round ligaments, one on each side of your uterus. They run from the top of the uterus, through the groin, and into the labia. As they stretch with the growth of your uterus, they're sensitive to sudden movements.

Why Does Round Ligament Pain Occur on One Side?

This is a common question asked during pregnancy. There are several reasons why you might feel round ligament pain on one particular side and not the other.
Is the Right Side More Commonly Affected?
  • Yes. Clinical observations and research indicate that round ligament pain is more common on the right side. This may be because you naturally tilt to the right while expanding.
  • Additionally, many people sleep more often on their right side or use their right side more for daily activities, which increases pressure on the ligament.
Can Daily Movement be the Reason for One-sided Pain?
  • Yes. Actions such as:
  1. Sneezing or coughing
  2. Moving suddenly
  3. Rolling over in bed
  4. Getting out of the car
It can suddenly stretch one ligament more than the other. If one side is already tighter, it reacts more intensely, leading to sharp pain.
Is Muscle Imbalance Responsible for this?
  • Your body naturally has a dominant side. Muscle imbalance may occur when you’re always using the same side of your body while performing activities like resting, carrying weight, or walking up stairs. This could increase pressure on one of your round ligaments.

How Does Round Ligament Pain On One Side Feel Like?

Round ligament pain varies for everyone, but the feeling might involve:
  • A sharp, stabbing soreness
  • It hurts suddenly or doesn’t go away
  • It aches when you move
The pain comes and goes within minutes and feels better when you rest.

When Does Round Ligament Pain Usually Start?

You may experience round ligament pain between weeks 14 and 28. The uterus expands rapidly during this time, and ligaments stretch quickly to adapt. However, it can occur earlier or later depending on:
  • Activity level
  • Body type
  • Number of pregnancies in the past

When This Might Feel Alarming:

You must get in touch with your healthcare provider if the pain:
  • Persists or becomes unbearable
  • High temperatures accompany it
  • It is associated with burning during urination
  • Comes with vaginal bleeding
  • Occurs with contractions

How Can You Ease the Round Ligament Pain?

While you cannot entirely control round ligament pain, you can reduce its frequency and intensity.
Move Gently
  • Sudden movements can trigger ligament pain. Standing up slowly, rolling over cautiously, and avoiding quick turns can help.
Use a Support Belt
  • A maternity support belt can help manage pressure on your ligaments as your belly expands.
Mindfully Bend
  • Bend cautiously at the waist when sneezing or coughing to reduce pressure on your ligaments.
Use Mild Compress
  • Using a mild, warm compress on the sore area can help loosen your muscles and ligaments.

What Could Be Done Further?

  • Try to move smoothly and steadily
  • Use cushions to support your body while resting
  • Wear comfortable footwear
  • Regularly practice gentle stretching
  • Stay hydrated
  • Discuss persistent pain with your healthcare provider

Social & Emotional Sides

Experiencing sudden pain or discomfort during pregnancy can be emotionally unsettling. You may feel anxious about your baby or frustrated when the discomfort continues to hamper your regular activities. Sharing your concern with your loved ones can help reduce stress.
Gentle help with movements, emotional reassurance, and understanding from loved ones can make this phase more manageable and less stressful.

How Does Mental Health Influence Physical Pain?

Stress can intensify muscle tension, worsening round ligament pain. Taking short breaks or practising deep breathing can help your body relax and ease discomfort.
Taking care of your emotional well-being supports your physical comfort as well.
Round ligament pain is a common pregnancy-related discomfort that mostly appears on one side due to the baby’s position, natural body alignment, and regular movement patterns. Though it can be uncomfortable, the pain is harmless and treatable. Knowing the causes and making a few lifestyle changes can help you manage the pain so you can feel better during pregnancy.
