Back pain is a common complaint during pregnancy due to the growing uterus and changes in posture. To manage back pain, consider practicing gentle exercises like stretching and yoga, which can strengthen your back and improve flexibility. It's also helpful to maintain good posture when sitting or standing. Using a supportive cushion while sitting can alleviate pressure on your back. If pain persists, don't hesitate to consult your midwife or GP, as they can recommend safe treatments or physical therapy options tailored to your needs.
