Why Your Lower Back Pain Might Actually Be a Pelvic Floor Problem

10/15/2026

Raise your hand if you've been dealing with lower back pain for way too long.

There are few things more frustrating than that constant, nagging ache that just will not go away. And what makes it even worse is that nothing seems to actually help. You've stretched. You've strengthened. You've tried massage, chiropractors, probably a new mattress or two.

Maybe you've even done physical therapy and felt some real relief, only to have it creep right back a few weeks later.

At some point, a lot of people just start assuming this is it. That back pain is going to be part of their life forever.

If you've tried everything for your back and nothing has stuck, there's a solid chance your pelvic floor has never been looked at. And for a lot of people, that's exactly the missing piece.

Your Core Is Not Just Your Abs

Most people picture the core as the abs. The six-pack. The thing you're working on in a plank.

But your core is actually a closed pressure system with four walls.

  • Diaphragm on top
  • Deep abdominal muscles around the sides
  • Deep spinal muscles along the back
  • Pelvic floor at the base

When all four are doing their job, pressure gets managed properly and your spine stays supported.

When one of them isn't pulling its weight, the others have to compensate. And an underperforming pelvic floor is one of the most commonly missed contributors to chronic back pain.

How Your Pelvic Floor Ends Up Causing Back Pain

Fascial Tension

Your whole body is wrapped in a web of connective tissue called fascia, and it connects everything. Tension in one spot travels to places that seem totally unrelated.

When your pelvic floor muscles are chronically tight, that tension moves right up through the fascia into your hips, sacrum, and lower back. Your back ends up caught in the middle of a problem that started somewhere else entirely.

Your Spine Loses a Stabilizer

The pelvic floor is a key stabilizer for your lumbar spine and pelvis. When it's not doing its part, your lower back muscles have to pick up the slack.

Do that for months or years and those overworked muscles get tight, exhausted, and painful. Which is exactly what you've been feeling.

Your Posture Quietly Adapts

When the pelvic floor can't support your pelvic organs well, your body compensates without asking you. Small shifts in how you stand, how you walk, how you hold your pelvis.

Those little adjustments load your lower back unevenly, and over time it adds up to real pain.

Your Breathing Falls Out of Sync

Your diaphragm and pelvic floor are supposed to move together with every breath. When that coordination breaks down, which happens constantly in people who are stressed or chest breathing, the whole pressure system stops working right.

Guess who absorbs the consequences? Your lower back.

Signs Your Back Pain Has a Pelvic Floor Component

If any of these sound familiar alongside your back pain, it's worth asking about a pelvic floor assessment.

  • Pain that's worse after sitting or standing for a while
  • Pain that flares up around your period
  • Hip tightness that shows up with the back pain
  • Any bladder or bowel symptoms like urgency, constipation, or trouble fully emptying
  • Pain that reaches into your tailbone or sacrum
  • Back pain that started or got worse after having a baby
  • Back pain that never fully resolved with regular PT

What a Pelvic Floor PT Catches That Others Miss

A standard PT evaluation looks at your lumbar spine, your joints, your back muscles. All of that matters and none of it is wrong.

But without assessing the pelvic floor, you're only seeing part of the picture.

A pelvic floor PT is trained to assess the tone, strength, coordination, and trigger points of those muscles, both externally and internally. That assessment picks up tension patterns and restrictions that are feeding your back pain but don't show up anywhere else. Not on imaging. Not on a standard exam.

And when those findings finally get treated, the back often responds in a big way, even for people who've been hurting for years.

A More Complete Way to Approach This

Chronic back pain is exhausting. It affects everything, from how you sleep to what you're willing to do on a Saturday.

If you've been treating your back on its own and not getting results that last, it's worth looking at the whole system.

At Lynne DiPirro Performance, we look at the pelvic floor, your breathing patterns, the fascial connections, your posture, and the daily movement habits that determine how much load your back is absorbing every day.

FAQ

Can a weak pelvic floor cause lower back pain?

Yes. A weak or poorly coordinated pelvic floor forces surrounding muscles, including your lower back, to overcompensate. That constant overwork creates chronic tension and pain.

Can tight pelvic floor muscles cause back pain?

Yes. Chronic pelvic floor tension travels through the fascia into your hips, sacrum, and lower back. Releasing it with manual therapy and relaxation work often brings real back relief.

Should I see a pelvic floor PT for lower back pain?

If your back pain started postpartum, comes with any pelvic floor symptoms, or hasn't responded to standard treatment, a pelvic floor assessment is absolutely worth doing.
