Many physical changes during pregnancy can impact your back and cause pain or discomfort. Back pain during pregnancy is almost always lower back pain within three categories: lumbar spine pain, posterior pelvic pain, or a combination of these two. The prevalence of back pain in pregnant women is estimated to be 50% in the first trimester, 40-70% in the second, and 70-80% in the third trimester. Just because back pain is common doesn’t mean you should have to suffer through it. This episode will discuss the causes of back pain during pregnancy, considerations for prevention, and techniques and tools to relieve pregnancy back pain.     Thank you to our sponsors   20% off Mommy Steps or Form insoles with the promo code FEET.
