Going the Distance with your Pregnancy
Pregnancy is extremely hard on the lower back as well as on the neck and shoulders. Examine the spine of an expectant mother from the side and it's easy to understand why they're in pain. Due to the increased development of the breast tissue, the shoulders are rounded forward, placing tremendous pressure on the neck and shoulders. The weight of the growing child places the lower back in a strenuous position.
The nine months of pregnancy brings many hormonal changes that relax the ligaments which stabilize the lower back and pelvis. As the pelvis rotates down in the front, the muscles of the lower back become short and tight, causing an increase in pressure on the pain sensitive joints of the lower back, producing achy lower back pain.
