Pregnant women with vague pain under the right rib cage can be treated as follows: 1. Patients are advised to keep bed rest in the near future. Sitting should be minimized, as there is a risk of significant pressure at this point, which can then lead to pain. After resting well, patients should get up and walk around more often and move around, keeping their chest up during walking. The patient also needs to pick looser clothing for this area to prevent friction and extrusion. 2. The patient can apply heat to the painful area. For this type of patient, it is recommended to apply self-heating materials such as warmers to the outer surface of the underwear to achieve a continuous hot compress effect. 3. Patients can apply medication such as Yunnan Baiyao spray to the painful area, but do not massage it afterwards. 4. Patients can do yoga moves for pregnant women. By doing this type of stretching indoors, the pain can often be significantly relieved. Finally, if the pain is not relieved by the above treatment, then the patient needs to go to an orthopedic clinic promptly.
