In briefFor about half of all pregnant women, low-back pain is inevitable. Physicians who can specify what type of back pain the patient has—lumbar, sacroiliac, or nocturnal—can institute targeted treatment that addresses the relevant pathophysiology. Acetaminophen and certain modalities such as icing the area are the basis of acute treatment in conjunction with ergonomic adaptation and a good low-back exercise program. This will help decrease stress on the low back, making back pain less likely. Before a woman becomes pregnant, encouraging her to become fit and resolving existing back problems is the key to back pain prevention.
