Why Do I Suddenly Have Lower Back and Hip Pain — What Is the Perimenopause Pelvic Floor Connection?

For the longest time, I thought I just slept wrong. Every single night. That dull, constant ache in my lower back and the weird stiffness in my hips just became my new normal — not unlike the way many women start to wake up with unexplained headaches — until I learned they weren't normal at all.

That new, nagging lower back and hip pain you're feeling might not be your mattress. During perimenopause, declining estrogen can weaken the muscles and connective tissues of your pelvic floor. Because your pelvic floor is a key part of your core stability, this weakness can cause other muscles in your back and hips to overcompensate, leading to the pain and instability characteristic of perimenopause pelvic floor pain.

What Exactly Is the Pelvic Floor, Anyway?

Honestly, I went decades without giving my pelvic floor a single thought. It's not something we really talk about. But it’s doing some heavy lifting, 24/7. Think of it as a muscular hammock or sling stretching from your pubic bone back to your tailbone. It’s a literal foundation.

This group of muscles supports your primary pelvic organs — your bladder, uterus, and rectum (Perimenopause - Pelvic Health Physical Therapy, 2024). But it doesn't stop there. It's a critical part of your "core," working with your deep abdominal muscles and diaphragm to stabilize your entire torso. When it's working right, you don't even notice it's there. You just feel strong and stable. When it's not… well, that’s when things start to feel off.

So How Does Perimenopause Cause Pelvic Floor Pain?

Here’s the connection I wish someone had explained to me years ago. Perimenopause is defined by wild hormonal swings, especially a steady decline in estrogen (Integrative approaches to perimenopause, 2024). Estrogen plays a huge role in keeping our connective tissues strong and elastic — think of it as the hormone that gives our tissues their "bounce."

As estrogen levels drop, the collagen-rich tissues in your pelvic floor can become thinner, weaker, and less flexible (Pelvic Floor Problems During Perimenopause, 2024). That supportive hammock starts to sag a little. This link between declining estrogen and muscle tone can lead to a whole host of issues, from bladder leaks to a feeling of heaviness, and for many of us, it can be a source of what feels like mysterious perimenopause pelvic floor pain.

Why Does Perimenopause Pelvic Floor Pain Feel Like an Aching Back?

This was the biggest lightbulb moment for me. I was so focused on my back, I never considered the problem was coming from the front. When your pelvic floor isn't providing a stable base, your body is smart — it tries to find stability elsewhere. So, other muscles have to pick up the slack.

Your hip flexors, glutes, and lower back muscles start working overtime to hold you upright and steady. This overcompensation leads to muscle imbalances, altered posture, and trigger points that can radiate pain directly to your lower back and hips (What Connects Your Menopause Back Pain and Your Pelvic Floor, 2025), sometimes alongside other muscular issues like twitches and spasms when you're trying to sleep. That’s why your attempts to stretch your back might not be working. The source of the problem isn't where you feel the pain. It’s a classic case of mistaken identity, and it's a common contributor to perimenopause pelvic floor pain and what many experience as hormonal lower back pain.

What This Means for You

First, take a breath. Knowing the "why" is a huge step. It's not just in your head, and it's not just "getting old." There's a real, biological reason for what you're feeling. But it's also a signal to listen to your body in a new way. And please, don't just jump into doing hundreds of Kegels.

For some women, the pelvic floor muscles are actually too tight (hypertonic), and strengthening exercises can make the pain worse. One of the most helpful first steps you can take is to get a proper evaluation from a pelvic floor physical therapist. They can determine exactly what your body needs — whether that’s strengthening, relaxation, or a combination of both. It's targeted, specific care that can make all the difference.
