Why Many Moms Experience More Pain at 6 Weeks Than 6 Days Postpartum (And Why That’s Normal)

If you’re a new mom who felt surprisingly okay in the first few days after birth, only to feel worse weeks later, you’re not imagining things.

In clinical practice, this pattern is extremely common.

Six weeks postpartum is often when cumulative physical load exceeds recovery capacity.

In fact, one of the most common things I hear from postpartum moms is this:

“I thought I’d feel better by now… why do I actually hurt more?”

The truth is, six weeks postpartum is often more physically demanding on the body than six days postpartum, and there are clear, evidence-based physiological reasons why.

Let’s unpack what’s happening.

1. The Early Postpartum “Buffer” Wears Off

In the first few days after birth, your body is still benefiting from a hormonal cushion:

• Elevated oxytocin (bonding + pain modulation)

• Residual endorphins from labour

• Adrenaline from the birth experience

  
  

Often: more rest, more support, fewer physical demands.

Many moms are also still being taken care of by partners, family, or hospital staff.

By 4–6 weeks, that buffer fades.

Hormones shift dramatically, support decreases, and real life kicks in.

From a nervous system perspective, this is when cumulative load begins to exceed recovery capacity.

2. Relaxin Is Still Elevated—But Stability Is Lower

Relaxin, the hormone that softens ligaments and joints during pregnancy and birth, does not disappear immediately after delivery. It can remain elevated for several months, especially if breastfeeding.

What that means:

• Joints (pelvis, SI joints, spine) are still less stable

• Muscles are often fatigued or inhibited

The body is being asked to do more with less support.

So while tissues are still vulnerable, moms are:

• Carrying babies

• Feeding for hours a day

• Lifting car seats

• Walking more

• Returning to exercise or work

This creates a biomechanical mismatch between tissue capacity and physical demand.

3. Postural Strain Accumulates

New motherhood is incredibly physical, but not always in balanced ways.

By six weeks postpartum, many moms are spending hours:

• Leaning forward to feed

• Looking down while holding baby

• Sitting unsupported

• Sleeping in awkward positions

• Carrying weight asymmetrically

Over time, this leads to:

• Neck and shoulder pain

• Mid-back and rib discomfort

• Low back and pelvic pain

• Wrist and elbow strain (“mommy thumb”)

Pain often peaks later because tissue irritation and muscular compensation build gradually over weeks, not days.

4. Core Dysfunction Is Common After Pregnancy

After pregnancy and birth, the core system (deep abdominals, pelvic floor, diaphragm, spinal stabilizers) often isn’t firing optimally, even if you feel “cleared” at six weeks.

This can create:

• Pelvic instability

• Compensatory muscle tension

• Poor load transfer through the pelvis and spine

Clearance at six weeks does not mean full recovery. It simply means healing is progressing normally. Functional strength and coordination often take much longer.

5. Sleep Deprivation Increases Pain Sensitivity

Chronic sleep disruption:

• Increases inflammation

• Lowers pain thresholds

• Reduces tissue recovery

• Impairs nervous system regulation

• 
  

By six weeks, exhaustion often becomes cumulative, and pain feels more intense when the nervous system is depleted. When the brain is under-recovered, it amplifies pain signals.

6. Cultural Expectations Don’t Match Physiological Reality

There’s a quiet but powerful cultural message that by six weeks postpartum, you should be:

• “Back to normal”

• Exercising again

• Cleared and capable

• 
  

But healing isn’t linear. When pain shows up at six weeks, many moms feel confused, discouraged, or even ashamed. Clinically, this timing is not unusual. It is predictable.

Your body is still adapting to new physical demands, hormonal shifts, and sleep disruption.

7. What Can Help With Postpartum Pain?

Postpartum pain is not something you have to “push through.” 

Supportive care may include:

• Chiropractic assessment of pelvic and spinal alignment

• Addressing joint mobility and stability

• Nervous system regulation

• Postural support and feeding ergonomics

Gradual, appropriate movement, not rushing recovery. Individualized postpartum care focuses on restoring coordination, reducing compensatory tension, and improving load tolerance, not simply managing symptoms.

The goal isn’t to “fix” you, it’s to support your body as it adapts to motherhood. Postpartum care shouldn’t end at delivery or at six weeks. You deserve evidence-informed support through the first few months of motherhood and beyond.
