Back Pain in Pregnancy: What Helps and What to Watch

Back Pain in pregnancy: how to think about it

ACOG and NHS both describe back pain as one of the most common pregnancy complaints, affecting a majority of people. The mechanisms are mechanical rather than pathological: the growing uterus shifts the centre of gravity forward, abdominal muscles stretch and support the spine less, and pregnancy hormones increase ligament laxity in the pelvis, so joints move more than usual. That combination puts more load on the lower back. Because the cause is structural, the guidance focuses on posture, gentle strengthening activity, supportive footwear and heat rather than on medication. Physiotherapy referral is part of NHS guidance for persistent cases. The reason the advice includes red flags is that a small number of causes are not mechanical: urinary infection, preterm labour and, rarely, other problems can present as back pain, so pain with fever, bleeding, burning on urination or regular tightening is treated differently.

Back Pain: safer choices

• Staying gently active. NHS and ACOG both point to exercise rather than rest, including walking, swimming and pregnancy-specific classes.
• Paying attention to posture: avoiding standing for long stretches, bending at the knees rather than the waist, and not carrying heavy loads on one side.
• Wearing flat supportive shoes, and using a firm mattress or a pillow between the knees when lying on your side.
• Applying warmth, such as a warm bath or heat pack on the back, which is commonly suggested for muscular pain.
• Asking about physiotherapy. NHS guidance mentions referral to physiotherapy for persistent pregnancy back and pelvic pain.
• Asking a pharmacist or midwife before taking painkillers, since paracetamol is the usual first choice and NSAIDs carry separate cautions.

Back Pain: what to avoid or double-check

• Do not ignore sudden severe back pain, particularly with bleeding, fever, painful urination, or regular tightening, which need prompt assessment.
• Avoid lifting heavy objects, and avoid twisting while lifting. Bend at the knees and keep the load close.
• Do not take ibuprofen or other NSAIDs on your own for pregnancy back pain. Ask first, particularly from 20 weeks where separate warnings apply.
• Avoid long periods standing still or sitting without changing position, both of which tend to make it worse.
• Do not assume all pelvic pain is ordinary back pain. Pelvic girdle pain is a distinct problem with its own physiotherapy treatment.
