As your belly continues to grow and your pregnancy hormones relax your muscles, your back may begin to ache later in the second trimester and throughout the third. Pain around the pubic bone is common in pregnancy and may cause you considerable discomfort and difficulty in walking, climbing stairs, and getting out of bed.
Acupuncture has been shown in clinical studies to be effective in reducing backache and increasing mobility. In one large study, 72% of pregnant women found acupuncture gave good relief for their backache. Acupuncture has also been shown to be more effective than physiotherapy in relieving pain and improving mobility for pelvic girdle pain.
You can often alleviate backache by using a chair with a good back support, wearing comfortable shoes, using ice and heat on the painful areas, and getting someone to occasionally give you a back massage.
