If you have back pain after having a baby, you should exclude gynecological infections. If the infection is ruled out, it is normal to have back pain. Since the body is weak after giving birth, and the birth itself will also put pressure on the waist, causing strain on the muscles of the waist. You need to pay more attention to rest, moderate hot compresses and physiotherapy or Chinese massage, reduce weight bearing, reduce strain and avoid prolonged standing and walking. Avoid prolonged weight-bearing activities, such as holding the baby for a long time, and avoid catching cold. In this case, if the symptoms still do not improve, you need to go to the hospital for further examination to clarify the diagnosis.
