Symphyseal Pain in Pregnancy: Causes, Relief, and When to See a Doctor
Symphyseal pain—discomfort around the pubic bone—is a common experience for many pregnant women, especially in the second or third trimester. This pelvic pain is linked to the loosening of joints in the pelvis as your body prepares for childbirth. While symphyseal pain is usually harmless, there are times when it’s important to get checked by a healthcare professional.
The main cause of symphyseal pain in pregnancy is hormonal changes, particularly the release of relaxin, which softens the pelvic joints to help your body get ready for labor. This process is natural, but it can sometimes lead to uncomfortable symptoms.
What is symphyseal pain? 🤰
Symphyseal pain occurs near the pubic bone (symphysis pubis) and may radiate to the hips, thighs, or lower back. The pain can feel dull, sharp, or pulling, and often worsens with movement, climbing stairs, turning in bed, or standing for long periods.
Biological background
During pregnancy, the hormone relaxin causes the pelvic joints—including the symphysis pubis—to become more flexible. This helps with childbirth but can reduce pelvic stability and trigger pain.
How does symphyseal pain develop?
The pelvic ring consists of three main joints: two sacroiliac (SI) joints and the pubic symphysis. Under the influence of relaxin, these joints loosen, and the symphysis may slightly separate, leading to tension and pain.
Common triggers
- Sudden movements (getting out of bed, turning)
- Climbing stairs or long walks
- Standing on one leg (while dressing)
- Lifting heavy objects
What are the symptoms of symphyseal pain?
- Pain at the pubic bone, worse with movement
- Difficulty walking, limping
- Pain radiating to the thighs, hips, or lower back
- Clicking or grinding sensation in the pelvis
Symptoms often develop gradually and may intensify as pregnancy progresses.
Everyday examples
- Getting out of bed in the morning is harder due to pubic bone pain
- Sharp pain in the pelvis when climbing stairs
- Sudden stabbing pain when standing on one leg to get dressed
- Aching or pulling pain in the hips after a long walk
How can you relieve symphyseal pain? 🌿
- Move slowly and avoid sudden changes in position
- Distribute weight evenly on both legs; avoid standing on one leg
- Rest frequently and avoid overexertion
- Use a pelvic support belt to stabilize the pelvis
- Learn specific exercises from a physical therapist
- Sleep on your side with a pillow between your knees
Possible risks and complications
Symphyseal pain is usually not dangerous, but rarely, the symphysis can separate excessively (symphysis pubis dysfunction), causing significant mobility issues. If pain is sudden, severe, or accompanied by swelling, bleeding, or fever, seek medical attention immediately.
When should you see a doctor? 🩺
- If pain is severe or restricts movement
- If you notice swelling, bleeding, or fever
- If pain starts suddenly, similar to an injury
- If daily activities become difficult
Your doctor may perform a physical exam and, if needed, imaging (such as ultrasound) to check your pelvis. Treatment may include physical therapy, a pelvic support belt, or rest.
