Low Back Pain After Delivery: Why It Happens and How Prolotherapy Can Help

Many women experience persistent low back pain after delivery, especially around the lower back, tailbone, or hip region. While this is often dismissed as a normal part of recovery, ongoing pain may indicate underlying issues such as sacroiliac joint dysfunction or ligament instability. This condition is often underdiagnosed and can continue for months if not addressed properly.

Why Does Low Back Pain Occur After Delivery?

Several physiological and lifestyle factors contribute to postpartum back pain:

1. Hormonal Changes
   During pregnancy, the hormone relaxin loosens ligaments to prepare the body for childbirth. However, this can also lead to:
   Pelvic instability
   Sacroiliac joint strain
2. Increased Pelvic Load
   The growing uterus increases pressure on the pelvis and lower back, placing stress on supporting ligaments.
3. Increased Lumbar Lordosis
   Changes in posture during pregnancy increase the curvature of the lower back, leading to mechanical strain.
4.  Repeated Pregnancies or Working Lifestyle
   Multiparous women
   Women with physically demanding jobs are more prone to ligament strain and instability.
5.  Postpartum Habits That Worsen Pain
   Prolonged sitting during feeding
   Using very soft beds or cushions
   Lifting the baby with weak abdominal muscles
   Poor core strength and lack of rehabilitation

What is the Actual Problem?

In many women, the root cause is not just muscle pain—it is:
Sacroiliac joint inflammation (sacroiliitis)
Ligament laxity leading to sacral instability
This explains why some patients do not improve fully with rest or basic physiotherapy alone.

What is Prolotherapy?

Prolotherapy (Proliferative Injection Therapy) was developed by George S. Hackett in the 1940s.
It is a regenerative treatment in which a medical solution is injected into weakened ligaments or tendons to stimulate healing and strengthen connective tissue.

What is in a Prolotherapy Injection?

A typical prolotherapy solution contains:
Dextrose (25%)
Xylocaine (local anesthetic)
Sterile water
Importantly:
It does NOT contain steroids or hormones

How Does Prolotherapy Work?

The injected dextrose acts as a mild irritant that:
Stimulates fibroblast activity
Promotes collagen formation
Strengthens weakened ligaments
Improves joint stability
This is especially beneficial in postpartum women where ligament laxity is the key issue.
Why is Prolotherapy Useful in Postpartum Low Back Pain?
In postpartum patients:
Sacroiliac ligaments (major weight-bearing ligaments) become weak
This leads to persistent instability and pain
Prolotherapy targets the root cause by strengthening these ligaments rather than just masking pain.
Is Prolotherapy Safe?
Compared to corticosteroid injections:
Prolotherapy aims at healing, not just temporary pain relief
It does not carry steroid-related side effects
It is generally safe when performed by trained professionals, with risks similar to standard joint injections.

How Many Sessions Are Needed?

Usually given once every 4–6 weeks
Total of 5–6 sessions, depending on response

Can Diabetic Patients Take Prolotherapy?

Yes. The amount of dextrose used is small and localized, and it . Does not significantly affect blood sugar levels, Does not cause weight gain

What Should You Do After the Injection?

To get the best results:
Avoid strong painkillers (like diclofenac, ibuprofen, coxibs)
Use paracetamol if needed
Take adequate:
Protein (fish, egg white, nuts)
Calcium, iron, and vitamins
Continue prescribed physiotherapy exercises
Maintain hydration (at least 2 liters/day)
Ensure proper sleep (7–8 hours)
Avoid stress

When Should You Consider This Treatment?

You should consider prolotherapy if:
Your back pain started after delivery
Pain persists beyond 3–6 months
Pain is near the tailbone or one side of the pelvis
Physiotherapy alone has not provided full relief

Final Takeway

Postpartum low back pain is not something you have to live with. When ligament instability is the cause, prolotherapy offers a promising, safe, and targeted treatment option that addresses the root problem.
If you are experiencing persistent pain after delivery, a proper evaluation can help identify whether this treatment is suitable for you
