Is it Pubic Symphysis Disorder or round ligament pain?

Pubic Symphysis Disorder (PSD or SPD) is a painful condition felt in the pubic area and is often mistaken for round ligament pain.  Unfortunately not a lot of OBs will give much heed to PSD (or even round ligament pain) because they cannot do much about it.  However, being able to distinguish the two will allow you to choose a more effective remedy in reducing your pain.

1. Where is the pain?

PSD: Almost always the pain is felt at the pubic symphysis joint—the bony part at the top of the pubic area—and will be very sore to the touch.  The pain usually radiates down into the groin and will often also radiate out into the hip joints.

Round Ligament: The pain is usually felt in the lower abdomen and slightly off to one (or both) sides.  It often radiates into the groin and/or around the sides to the flanks or hips.

2. What is the quality of the pain?

PSD:  Sharp and intense.  For some the pain feels like they are breaking open from the inside or their hip bones are grinding together.  Oftentimes a clicking sound is heard when walking or moving.

Round Ligament:  Also sharp and can be intense.  Many times the pain happens suddenly.

3. When is the pain felt?

PSD:  When standing, walking, shifting while sitting, and intensely when rolling over in bed.  The pain continues even after stopping the movement.

Round Ligament:  When performing sudden movements and usually diminishes if not goes away after a few seconds.

If you still aren't sure which it is here is a simple test: stand on one leg (please use your arms to support yourself when doing this).

PSD: You will experience increased pain or even an inability to stand on one leg (the other leg may give out).  You will find it difficult with activities like walking up stairs, raising one leg to put on pants, or getting in/out of a car.

Round Ligament: You will experience minimal, if any, change in pain and should find it easy to stand on one leg.

Here is a side note: Sciatica and sacroiliac joint dysfunction (SIJD) are sometimes co-conditions of PSD.  The presence of sciatica or SIJD does not rule out PSD, but it doesn’t guarantee it either.
