Postpartum Tailbone Pain: Why Your Coccyx Hurts After Birth and What Actually Helps

Tailbone pain after having a baby is common — but common does not mean normal. Because your pelvic floor muscles attach directly to the coccyx, tight or guarding muscles can keep pulling on that area long after delivery. Susan Winograd, MSPT explains what's really behind postpartum tailbone pain and what actually helps.

Your body is doing something extraordinary. Let's help it heal.

Whether you're preparing for birth or recovering from it, pelvic floor physical therapy makes a profound difference — less pain, faster recovery, and a stronger foundation for everything ahead. Susan has worked with pregnant and postpartum women for nearly 30 years.

You had a baby. And now, weeks or even months later, sitting feels like you’re sitting on a bruise.

Maybe it’s the moment you lower yourself onto the couch. Maybe it’s standing back up. Maybe it’s the drive to your pediatrician appointment, or the long stretch of holding and feeding your baby in the same position. Wherever it shows up, the pain is right there at the very bottom of your spine — sharp, tender, and impossible to ignore.

If that’s you, you’re not alone. Tailbone pain after pregnancy is very, very common.

But here’s what I want you to know, and it’s something we say all the time at Pelvicore because we mean it every single time: common does not mean normal.

What Is Postpartum Tailbone Pain (Coccydynia)?

Your tailbone — the coccyx — is the small, triangular set of fused bones at the base of your spine. Pain in this area is called coccydynia, and postpartum women are one of the groups most likely to experience it.

A little soreness in the first few weeks after delivery? That can happen. Your body has been through a tremendous amount, and some tenderness during early recovery isn’t unexpected.

But if you’re still having tailbone pain weeks or months later — or if it’s affecting your ability to comfortably sit, exercise, care for your baby, or simply get through your normal daily activities — it’s time to pay attention to the signals your body is giving you. That’s not a phase to wait out. That’s information.

Why Does the Tailbone Hurt After Pregnancy and Childbirth?

There are two main things happening, and most women only ever hear about the first one.

1. The Coccyx Can Be Compressed, Strained, or Pushed Backward During Delivery

During pregnancy and childbirth, your tailbone takes on real mechanical stress. As your baby moves through the pelvis, the coccyx can be compressed, strained, or even pushed backward out of its normal position.

This is especially common after:

  • A very long labor
  • Prolonged pushing
  • A vacuum or forceps-assisted delivery
  • Delivering a larger baby

Any of these can leave the coccyx irritated, hypermobile, or sitting in a position it wasn’t in before — and that irritation is what you feel every time you put weight through it.

2. Your Pelvic Floor Muscles Attach Directly to Your Tailbone

This is the piece almost nobody explains, and it’s often the reason tailbone pain lingers long after the tissues should have healed.

A lot of your pelvic floor muscles insert directly onto the tailbone. They are physically anchored there. So the coccyx isn’t just a bone that got bumped during delivery — it’s an attachment point for a muscle group that just went through one of the most demanding events of your life.

If those pelvic floor muscles are tight, overworking, or protecting that area after birth, they will keep pulling on the tailbone. And that constant pull generates pain — day after day, long after you’d expect to feel better.

This is why so many women get told “it should resolve on its own,” wait patiently, and then find themselves six months out still bracing every time they sit down. The bone may be fine. The muscles pulling on it are not.

What Helps Postpartum Tailbone Pain: 4 Places to Start

The good news is that there is a ton you can do. Here’s where I’d start.

Improve Your Sitting Alignment

Get the weight off the tailbone and off that pelvis. Most of us sit tucked back onto the sacrum and coccyx, which puts direct pressure exactly where it hurts. Shifting to sit up over your sit bones — the bony points you can feel underneath you — takes load off the tailbone immediately.

A wedge cushion or a cushion with a cutout at the back can help enormously in the meantime, particularly for long drives and feeding sessions.

Practice 360-Degree Breathing

360-degree breathing means allowing your ribcage to expand in all directions — front, sides, and back — rather than only lifting the chest or gripping the abdomen. This breathing pattern lets the pelvic floor lengthen and relax on the inhale, which is exactly what an overworking, guarded pelvic floor needs. It’s simple, it’s free, and it’s one of the most effective things you can do to give those muscles permission to let go of the tailbone.

Avoid Constipation

This one surprises people, but it matters more than you’d think. Straining on the toilet loads the pelvic floor and puts direct pressure through the coccyx, and postpartum constipation is extremely common. Staying hydrated, getting adequate fiber, using a footstool to bring your knees above your hips, and not holding your breath and bearing down all reduce that repetitive strain on an already irritated area.

See a Pelvic Floor Physical Therapist

Every postpartum mom should see a pelvic floor physical therapist — not just those with pain. A pelvic floor PT can assess whether your pelvic floor is actually recovering optimally, whether those muscles are tight and pulling on the coccyx, and whether your core system is coordinated.

That last part matters. Your diaphragm, deep abdominals, pelvic floor, and back muscles need to work well individually — but they also need to work together as a system. When one part is guarding or compensating, the whole system loads unevenly, and the tailbone often ends up absorbing the difference.

When to Get Help for Tailbone Pain After Birth

Reach out to a pelvic floor physical therapist if:

  • Your tailbone pain has lasted beyond the first several weeks postpartum
  • Sitting, standing up from sitting, or driving is consistently painful
  • The pain interferes with caring for your baby, exercising, or intimacy
  • You’re changing how you sit, move, or go about your day to avoid the pain
  • The pain is getting worse rather than better over time

You don’t need to wait until it’s unbearable, and you don’t need a certain amount of time to have passed. If it’s affecting your life, that’s reason enough.

You Don’t Have to Live With Tailbone Pain

What’s common is not normal. And feeling pain does not mean you have to accept it as your new baseline.

Postpartum tailbone pain is treatable. There are real, identifiable reasons it happens, and there are real, effective things that address it — starting with understanding the pelvic floor’s role in the whole picture.

If tailbone pain is part of your postpartum experience, we’d love to help you sort out what’s driving it.
