Back Pain In Pregnancy

Pregnancy, Back Pain and Posture

I guess I was a bit odd, because I didn't have much back pain in pregnancy when previously I did.  I believe some of my back pain was caused by hormonal fluctuations associated with my period (so when I was pregnant, I no longer had the fluctuating hormones).

One doctor described it at referred pain.   However, this article explains why women have back pain and some ways to deal with it. Read more:

During antenatal care, it is essential that pregnancy care providers and perinatal educators identify women who may be at risk for long-term back pain. Consequently, special attention can be focused on the back during labour and delivery and, again, at postnatal visits so that these women can be properly assessed and correct treatment organised. The need for improved assessment of pain as part of postnatal care has recently been described in an earlier issue of this journal (Stainton, Edwards, Jones, & Switonski, 1999).

Assessment of posture, history, and exercise pattern—particularly during the early stages of pregnancy—is an important feature in preventing a pregnant woman's experience with back pain/discomfort (Waddell & Turk, 1992). Much more focus is spent on ultrasound and other investigations that address the front of a woman's body during pregnancy compared to the lack of attention and technology for investigating the back of her body
