How is non-specific low back pain different in pregnancy?

As pregnancy progresses, the abdomen grows and balance, walking pattern and sleeping positions may change. Muscles and joints around the lower back and pelvis can therefore feel more loaded during standing, turning or climbing stairs. Non-specific pain still means no single harmful structure has been identified, but pregnancy makes it especially important to consider urinary, pelvic and obstetric symptoms alongside back symptoms. Pain can occur in pregnancy without signalling a serious problem, yet it should not be self-diagnosed from location alone.

Tell your maternity clinician or doctor about new or persistent pain before starting medicines. Change positions, use pillows for support, choose comfortable footwear and take gentle walks if tolerated. A pregnancy-informed physiotherapist can teach pelvic and trunk exercises, lifting strategies and ways to turn in bed. Avoid exercises or manual treatments that cause worsening pain, dizziness, bleeding or contractions, and check any medication with your maternity team.

Contact your maternity service promptly for back pain with vaginal bleeding, fluid leakage, regular tightening, fever, painful urination or severe abdominal pain. Urgent assessment is needed for new leg weakness, numbness around the saddle area, or loss of bladder or bowel control. Seek review when pain is sudden, severe, worsening or interfering with walking, sleep or daily care.

Ask whether your symptoms fit mechanical back pain, which movements and medicines are suitable at your stage of pregnancy, and whether a physiotherapy referral would help. Ask which maternity warning signs require immediate contact.
