Back pain is one of the most common physical complaints among new mothers. While some degree of discomfort is expected due to physical and hormonal changes during pregnancy and childbirth, persistent or severe back pain after delivery can be a warning sign of an underlying spinal issue.
At The Spine Foundation, we regularly see women – particularly in underserved and rural communities – who attribute disabling back pain to “normal post-delivery weakness.” Unfortunately, this belief often delays proper diagnosis and treatment, allowing preventable spinal conditions to worsen.
What causes back pain after childbirth?
There are several physiological and biomechanical reasons why new mothers experience back pain after delivery:
- Hormonal changes. During pregnancy, the body produces Relaxin, a hormone that loosens ligaments in the pelvis to facilitate childbirth. This laxity can destabilize the spine and pelvis, leading to pain that continues after delivery.
- Postural stress. Feeding the baby, lifting the infant repeatedly, and poor sleeping postures (especially on thin mattresses or without spinal support) can strain the lumbar and thoracic spine.
- Weakened core and pelvic muscles. Pregnancy stretches and weakens abdominal muscles, which support the lower back. When these muscles are weak, more load falls on the spine.
- Epidural or spinal anaesthesia. Although generally safe, spinal anaesthesia can sometimes cause local tenderness or mild back pain at the site of injection. This typically resolves within a few days. In most women, Mild back pain starts improving within 6 to 12 weeks postpartum With rest, proper posture, and light physical therapy.
When back pain may indicate something serious
You should not ignore back pain that:
- Persists beyond three months
- Radiates to the legs (sciatica-like pain)
- Comes with numbness, tingling, or weakness
- Leads to bladder or bowel control problems
- Worsens with coughing, sneezing, or prolonged sitting
- Disrupts daily functioning or sleep
These symptoms could indicate underlying spinal pathologies that require medical attention.
When back pain may indicate something serious
- Herniated disc. Increased intra-abdominal pressure during childbirth can worsen an existing disc bulge or cause a herniation. If the disc presses on a spinal nerve, it can cause leg pain (sciatica), tingling, or even foot drop.
- Tuberculous spondylodiscitis (spinal TB). In India, spinal tuberculosis is still prevalent – especially among women with poor nutrition and limited access to healthcare. Spinal TB often starts with dull back pain, worsens over months, and can lead to spinal cord compression and paralysis if untreated. In a 2023 screening camp in rural Maharashtra, The Spine Foundation identified several postpartum women with spinal TB; none had been diagnosed until their symptoms became severe.
- Sacroiliac joint dysfunction. Pregnancy loosens the sacroiliac (SI) joints, connecting the spine and pelvis. If this joint does not stabilise after childbirth, it can cause persistent lower back and buttock pain.
- Postpartum osteoporosis. Though rare, this condition can cause spinal compression fractures in women who are calcium- and vitamin D-deficient, particularly if they breastfeed exclusively without supplementation.
- Lumbar spondylolisthesis. In some cases, one vertebra slips over another, leading to instability. Hormonal relaxation and delivery stress can worsen this condition.
Why many women delay seeking help
Several social and systemic factors contribute:
- Cultural belief that pain after childbirth is “normal” and must be endured.
- Lack of female-centric orthopaedic care in primary health centers.
- Focus on the newborn, often at the cost of the mother’s health.
- Financial or geographical barriers to reaching spine specialists.
This is particularly evident in rural and tribal areas, where The Spine Foundation has worked for over two decades. During our community outreach camps, we consistently meet women who have lived with back pain for years without diagnosis.
When should you see a doctor?
You should consult a spine specialist if:
- Your pain doesn’t improve by 6–12 weeks.
- You feel pain, numbness, or tingling in the legs.
- You notice new weakness or difficulty walking.
- You experience urinary incontinence, loss of bowel control, or saddle anaesthesia (numbness in the inner thighs or buttocks).
- The pain is worsening, unexplained, or accompanied by fever or weight loss.
How diagnosis is made
A spine specialist may advise:
- Clinical evaluation
- X-rays to check for bone structure abnormalities
- MRI to assess discs, spinal cord, and signs of infection
- Blood tests if infection or inflammation is suspected
Treatment options
Depending on the diagnosis, treatment may include:
- Physiotherapy and postural correction
- Bracing for support
- Medications for infection or inflammation
- Surgical intervention, if spinal cord compression or instability is present
- Nutritional rehabilitation (calcium, vitamin D)
Importantly, early diagnosis leads to better outcomes, especially in infections like spinal TB, which respond well to antibiotics if caught early.
Spine health is women’s health
Ignoring chronic back pain after childbirth not only affects a mother’s quality of life but also her ability to care for her child and return to daily activities.
At The Spine Foundation, we urge ASHA workers, gynaecologists, and family members to recognise the importance of spine care for postpartum women. Our Rural Spine Care Initiative includes screening camps focused specifically on women’s spine health – especially in underserved areas.
Takeaway
Back pain after childbirth is not always “just fatigue.” If it persists or worsens, it may be a sign of something deeper.
Spinal infections, disc issues, or postural dysfunctions can be treated effectively – if identified in time. New mothers deserve the same level of care and attention as their newborns.
If you or someone you know is suffering from back pain after childbirth, don’t wait. Seek care today.
