Keeping the reproductive tract scrupulously clean, and building up muscle tone through prescribed exercises, should suffice to keep lower back pain in early pregnancy within entirely bearable limits. The obstetrician in charge of a pregnancy is the best person to decide on the extent and types of exercises to keep the back muscles strong and supple, while personal habits, including those of a partner, are crucial for keeping the reproductive system free of infections which can cause the womb to swell unnecessarily. Physical examination and tests do reveal the presence of any infection, and a doctor can prescribe treatment for both partners to deal with it.
