A sore throat after pregnancy can be a symptom of laryngitis, chronic pharyngitis, or an upper respiratory infection. Since you can’t take some regular medications orally during pregnancy, how to deal with it becomes a tricky issue. You can drink a moderate amount of water, while maintaining adequate rest. You can also apply mouthwash locally to wash away some bacteria and reduce the symptoms. At the same time, you can apply saline, physiological sea salt water for oral spraying, or through the nasal cavity for nasal rinsing, which can make the inflammation subside and also reduce the symptoms. Because physiological sea salt water has the function of disinfection and sterilization, it is also a common practice in clinic, so patients are advised to try it.
