A common plague for ladies during pregnancy is back pain. Back pain is very common because no matter how careful you are, you're going to gain weight in pregnancy and that's going to add to how your back feels. You have a pregnant uterus that's growing, so that really causes a lot more stress on the back. The hormone changes in pregnancy actually can affect the ligaments' support system.
Rick Olderman, Physical Therapy, answeredYour back is more inclined to experience pain as your pregnancy progresses. The increased curvature of the lumbar spine causes stress to the tissues surrounding the most mobile vertebrae, usually at the lumbosacral junction. This also affects how you bend forward and straighten back up. All these factors in combination with a wider pelvis contribute to sciatic pain.
The pelvis, the keystone of spinal mechanics, often becomes anteriorly tilted (when the top of the pelvis tilts forward) as your pregnancy progresses. This tilt becomes more or less permanent because the muscles in the front of your pelvis shorten to accommodate the tilt; if they're not stretched later after the baby is born, they will continue to maintain the anterior pelvic tilt. In terms of movement, this anterior tilt keeps your spine in excessive extension when you bend over and stand up. This creates stress, and therefore pain, at the most mobile vertebrae.
