Is back pain common during pregnancy? 

Author: Harry Whitmore, Medical Student | Reviewed by: Dr. Stefan Petrov, MBBS

Yes, back pain is extremely common during pregnancy, affecting more than two thirds of expectant mothers in the United Kingdom. While it can be uncomfortable, it is usually a normal part of the body’s adjustment to the growing baby. According to NHS and NICE clinical guidelines, most pregnancy related back pain is mechanical, meaning it is caused by the physical changes in your posture and the shifting of your centre of gravity. Understanding the causes and using gentle management strategies can help you remain active and comfortable throughout your pregnancy. 

What We’ll Discuss in This Article 

  • The role of hormones (Relaxin) in joint stability 
  • How your centre of gravity changes as the baby grows 
  • The difference between back pain and Pelvic Girdle Pain (PGP) 
  • Safe ways to manage pain without medication 
  • NHS recommended exercises for pregnancy 
  • Identifying when back pain requires urgent attention 

Why Back Pain Occurs in Pregnancy 

Several factors combine to put extra strain on your spine during these nine months. 

  • Hormonal Changes: During pregnancy, your body produces a hormone called Relaxin. Its job is to loosen the ligaments in your pelvis to prepare for birth. However, this also makes the joints in your spine and pelvis less stable, leading to aches and pains. 
  • Shifting Centre of Gravity: As your uterus expands, your centre of gravity moves forward. To compensate and avoid falling, most women lean back, which increases the arch in the lower spine and strains the back muscles. 
  • Weight Gain: The additional weight of the baby, placenta, and amniotic fluid puts direct mechanical pressure on your spinal discs and the small joints of your back. 
  • Abdominal Muscle Stretching: As your tummy grows, your abdominal muscles stretch and become less able to support your back, forcing your spinal muscles to work much harder. 

Back Pain vs. Pelvic Girdle Pain (PGP) 

It is important to distinguish between general back pain and PGP (formerly known as symphysis pubis dysfunction). 

  • Back Pain: Usually felt as a dull ache across the lower back or shoulders. It often worsens at the end of the day or after prolonged standing. 
  • Pelvic Girdle Pain: This is felt lower down, around the pubic bone or the sacroiliac joints at the back of the pelvis. It can cause sharp pain when walking, climbing stairs, or turning over in bed. 

Safe Ways to Manage Pain 

The NHS recommends several non-invasive strategies to help settle pregnancy related back pain: 

  1. Posture Awareness: Try to stand tall with your bottom tucked in and your shoulders back. Avoid crossing your legs when sitting. 
  1. Supportive Footwear: Wear flat shoes that provide good arch support and cushioning to help absorb the impact of walking. 
  1. Sleeping Support: Sleep on your side with a pillow between your knees and a wedge pillow under your bump to keep your spine aligned. 
  1. Heat Therapy: A warm bath or a heat pack (wrapped in a towel) on your lower back can help relax tight muscles. 

Exercise and Physiotherapy 

Staying active is one of the best ways to prevent back pain from worsening. 

  • Pelvic Tilts: This gentle exercise helps strengthen your core and stretch your lower back muscles. 
  • Aquanatal Classes: Exercising in water takes the weight off your joints and allows for pain free movement. 
  • NHS Physiotherapy: If your pain is affecting your daily life, your midwife or GP can refer you to an obstetric physiotherapist who specialises in pregnancy related musculoskeletal issues. 

Conclusion 

While back pain is a very common part of pregnancy, you do not have to suffer in silence. Making small adjustments to your posture, staying gently active, and using supportive pillows can make a significant difference. Most pregnancy related back pain resolves quickly after birth. However, if you experience sudden, severe back pain accompanied by vaginal bleeding, fever, or pain when peeing, contact your midwife or GP immediately. If you have any loss of bladder or bowel control, call 999 as this is an emergency. 

Can I take painkillers for back pain during pregnancy?

Paracetamol is generally considered safe, but you should avoid ibuprofen and other NSAIDs unless specifically prescribed by a doctor. Always consult your pharmacist or midwife first.

Should I use a maternity support belt? 

Many women find that a support belt helps take the weight off their pelvis and lower back, but it should be used alongside strengthening exercises, not instead of them.

When does pregnancy back pain usually start?

It most commonly begins in the second half of pregnancy (around week twenty), but for some women, it can start much earlier due to hormonal changes.

Can I have a massage for back pain while pregnant? 

Yes, but ensure the therapist is qualified in prenatal massage. You should avoid lying flat on your back after sixteen weeks; a side lying massage is much safer.

Why is my back pain worse when I turn over in bed? 

This is often a sign of Pelvic Girdle Pain. Keeping your knees together while you roll can help reduce the strain on your pelvic joints.

Will back pain affect my labour?

Most women with back pain go on to have normal births. Your midwife can suggest different positions, such as being on all fours, to help manage back discomfort during labour.

Does a TENS machine help? 

TENS machines are often used for pain relief during labour, but you should check with your midwife before using one for general back pain during pregnancy.
