If a pregnant woman takes a left-sided sleeping position that causes rib pain, the following treatment measures can be taken: 1. Patients are advised to first change their sleeping position. Generally, for this case, it is necessary to adopt a right-side sleeping position and not to adopt a flat or prone position. Because these two sleeping positions can cause the fetus to be affected or the mother’s abdominal aorta to be compressed, resulting in poor circulation. 2. It is recommended that the patient get up and move around more during waking hours. It is generally recommended that the patient do flat road walking, or climbing stairs and other activities.3. The patient can apply hot compresses to the painful parts, such as hot water bags to the painful parts, but be careful not to massage.4. It is recommended that the patient can do stretching exercises to relieve this type of pain, such as the patient can find yoga videos for pregnant women, and then follow them. If you do stretching movements involving the trunk, you can significantly relieve this type of pain. If taking this approach does not work well, the patient should still seek medical help to deal with it.
