Unfortunately, back pain is very common in pregnancy. Usually it will go away on its own within the first year after delivery. If it doesn't get better in that time, you may have a more chronic problem. It's estimated that about one-fourth of all women with chronic back pain develop the condition during pregnancy. There are many ways to approach chronic back pain. See your health care provider if your back pain feels like it is getting worse, is severe, or doesn't go away with time.
