Round Ligament, SI Joint, or Pelvic Girdle Pain? Telling Pregnancy Pain Apart

Pregnancy is an incredible journey, but it also places remarkable physical demands on the body. As your baby grows, your posture changes, your center of gravity shifts, and hormones prepare your joints and ligaments for childbirth. These changes are completely normal, but they can also lead to aches and pains that sometimes leave expectant mothers wondering what's actually causing their discomfort.

Is it round ligament pain? Is it your sacroiliac (SI) joint? Could it be pelvic girdle pain?

These conditions can produce similar symptoms, yet they involve different structures and often feel different depending on the activity you're doing. Understanding the differences can help you communicate more effectively with your healthcare provider and seek appropriate treatment.

If you're searching for a pelvic girdle pain pregnancy chiropractor, knowing how these common pregnancy-related conditions differ is an excellent place to start.

Why Pregnancy Causes So Many Different Types of Pain

During pregnancy, your body undergoes significant musculoskeletal changes.

Several factors contribute to discomfort, including:

• Increased body weight
• Changes in posture
• A forward shift in your center of gravity
• Hormonal changes that increase ligament flexibility
• Growing pressure on the pelvis
• Altered walking mechanics

As pregnancy progresses, the muscles, joints, and ligaments surrounding the pelvis work harder to provide stability while accommodating your growing baby.

Because multiple structures are adapting simultaneously, discomfort can develop in different locations for different reasons.

What Is Round Ligament Pain?

Round ligament pain is one of the most common causes of abdominal discomfort during pregnancy.

The round ligaments help support the uterus as it grows. As pregnancy progresses, these ligaments stretch considerably, particularly during the second trimester.

What Does Round Ligament Pain Feel Like?

Many women describe round ligament pain as:

• A sudden sharp pain
• A brief pulling sensation
• Discomfort in the lower abdomen
• Pain extending into the groin

It often occurs:

• When standing quickly
• Rolling over in bed
• Coughing
• Sneezing
• Laughing
• Changing positions

Unlike some other pregnancy-related pain, round ligament discomfort usually lasts only seconds or a few minutes before easing.

What Is SI Joint Pain?

The sacroiliac (SI) joints connect the base of the spine to the pelvis.

These joints play an essential role in transferring forces between the upper body and legs.

During pregnancy, increased ligament flexibility and changes in body mechanics can place additional stress on these joints.

Common Symptoms of SI Joint Pain

Women experiencing SI joint dysfunction often report:

• Pain on one side of the lower back
• Pain near the dimples above the buttocks
• Discomfort while walking
• Difficulty climbing stairs
• Pain when standing on one leg
• Discomfort rolling over in bed

SI joint pain often feels deeper than round ligament pain and is usually located toward the back of the pelvis rather than the front of the abdomen.

Many women specifically search for SI joint pain pregnancy relief because the discomfort can significantly affect daily activities.

What Is Pelvic Girdle Pain?

Pelvic girdle pain (PGP) is a broader term describing pain arising from the joints, ligaments, and muscles of the pelvis during pregnancy.

It may involve:

• Both SI joints
• The pubic symphysis
• Surrounding muscles
• Multiple pelvic structures simultaneously

Unlike isolated SI joint pain, pelvic girdle pain often affects several areas at once.

Common Symptoms of Pelvic Girdle Pain

Symptoms may include:

• Pain across the back of the pelvis
• Pain in the hips
• Groin discomfort
• Pubic bone pain
• Pain when walking
• Difficulty turning in bed
• Pain climbing stairs
• Difficulty standing on one leg
• Discomfort getting into or out of a vehicle

Pelvic girdle pain can range from mild to quite limiting depending on its severity.

How These Conditions Differ

Although they sometimes overlap, each condition has distinguishing characteristics.

Round Ligament Pain

Typically:

• Located in the front of the lower abdomen
• Sharp and brief
• Triggered by sudden movement
• Usually resolves quickly

SI Joint Pain

Typically:

• Located in the lower back or buttock
• Often one-sided
• Worse with standing or walking
• May persist throughout the day

Pelvic Girdle Pain

Typically:

• Involves multiple pelvic regions
• May affect both sides
• Can include front and back pelvic pain
• Frequently interferes with walking and daily movement

Because symptoms sometimes overlap, a comprehensive evaluation is often necessary to determine which structures are contributing to discomfort.

Why Hormones Play an Important Role

Pregnancy hormones, particularly relaxin, increase ligament flexibility in preparation for childbirth.

This increased flexibility is normal and beneficial.

However, greater ligament flexibility also means joints may have less natural stability.

As muscles work harder to compensate, discomfort may develop throughout the pelvis and lower back.

These hormonal changes are one reason pregnancy-related pelvic pain can fluctuate from day to day.

When Should You Seek Evaluation?

Some pregnancy discomfort is expected.

However, persistent pain deserves evaluation.

Consider speaking with your healthcare provider if pain:

• Makes walking difficult
• Interferes with sleep
• Limits daily activities
• Continues worsening
• Causes significant difficulty climbing stairs
• Makes standing uncomfortable
• Persists despite rest

Early assessment often helps identify contributing factors before symptoms become more severe.

How Chiropractic Care May Help

Many pregnant women seek a pelvic girdle pain pregnancy chiropractor to help manage musculoskeletal discomfort conservatively.

Chiropractic care during pregnancy focuses on improving movement while accommodating the unique physical changes occurring throughout each trimester.

Treatment is modified specifically for pregnant patients and may include:

• Gentle chiropractic adjustments
• Pelvic mobility assessment
• Soft tissue therapy
• Pregnancy-specific positioning
• Movement recommendations
• Postural education

The objective is to improve joint function and reduce mechanical stress contributing to discomfort.

Can Chiropractic Help SI Joint Pain?

Many women searching for SI joint pain pregnancy relief are experiencing discomfort related to altered pelvic mechanics.

Following a thorough evaluation, chiropractic care may help improve movement of the sacroiliac joints while addressing surrounding muscle tension and movement restrictions.

Treatment is always individualized based on your symptoms, stage of pregnancy, and overall health.

What About the Webster Technique?

Some pregnant women receiving chiropractic care may also hear about the Webster Technique.

The Webster Technique is a specialized chiropractic assessment and adjustment protocol designed to evaluate pelvic biomechanics during pregnancy.

Its purpose is to improve maternal pelvic function.

It is not intended to turn breech babies or guarantee easier labor.

If appropriate, your chiropractor will determine whether elements of the Webster Technique should be included in your care.

Self-Care Strategies That May Help

Depending on your symptoms, your healthcare provider may recommend:

• Avoiding prolonged standing
• Sleeping with a pillow between your knees
• Changing positions slowly
• Wearing supportive footwear
• Gentle stretching
• Activity modification
• Pregnancy-specific exercises

Because every pregnancy is different, recommendations should always be individualized.

When Pain Is Not Normal

Although musculoskeletal discomfort is common during pregnancy, some symptoms require prompt medical evaluation.

Contact your obstetric provider immediately if you experience:

• Vaginal bleeding
• Fever
• Severe abdominal pain
• Fluid leakage
• Regular contractions before term
• Significant decrease in fetal movement
• Severe pelvic pain accompanied by other concerning symptoms

Your chiropractor should also encourage immediate medical evaluation if these symptoms occur.

Choosing the Right Pregnancy Chiropractor

Not every chiropractor has extensive experience working with pregnant patients.

When choosing a provider, look for someone who:

• Has experience treating pregnant women
• Performs comprehensive evaluations
• Uses pregnancy-specific treatment positioning
• Modifies care throughout pregnancy
• Communicates with your obstetric provider when appropriate

Comfort, communication, and individualized care are essential throughout pregnancy.

Understanding Your Pain Is the First Step Toward Relief

Pregnancy-related discomfort isn't always caused by the same structure. Round ligament pain, SI joint dysfunction, and pelvic girdle pain each involve different parts of the body and often require different approaches to management. Understanding where your pain originates helps guide appropriate treatment while providing reassurance that many pregnancy-related musculoskeletal conditions can be managed conservatively.

If you're looking for a pelvic girdle pain pregnancy chiropractor, a comprehensive evaluation can help determine whether your symptoms are related to pelvic mechanics, SI joint dysfunction, or other musculoskeletal changes associated with pregnancy. Likewise, women seeking SI joint pain pregnancy relief may benefit from personalized care that focuses on improving movement, reducing mechanical stress, and supporting comfort throughout pregnancy.



Every pregnancy is unique. Working closely with both your obstetric provider and an experienced prenatal chiropractor allows you to receive individualized care that prioritizes your health, your comfort, and the well-being of your growing baby.
