What causes back pain during pregnancy? You can blame your growing uterus for your aching back. Your expanding uterus shifts your center of gravity and stretches out and weakens your abdominal muscles. This changes your posture and puts a strain on your back. At Donay Chiropractic we can help! You can start chiropractic care as soon as your pregnancy is confirmed. After you have a baby, your body goes through some major changes. Your spine and pelvis are especially vulnerable to misalignment during this time. That's why getting regular chiropractic adjustments at our office can be so beneficial for new moms. Adjustments can help relieve pain, improve your range of motion, and promote healing.
