Coughing and sore throat during the month is mostly caused by cold and flu. You should drink plenty of warm water for conservative treatment, and if the symptoms continue to be unimproved, you should go to the hospital in time, and choose the medication that has less impact on breastfeeding for treatment. 1. Coughing and sore throat can be caused by a weak immune system and a cold. As you are breastfeeding, you should avoid cross-infection with your baby and use conservative treatment, drink more warm water to help dilute phlegm and promote phlegm expulsion, thus promoting cough recovery. 2. Due to breastfeeding during labor and delivery, care needs to be taken with medication, otherwise the baby will be affected. If the symptoms worsen or are not relieved, it is recommended to visit the hospital in time and choose the appropriate medication for treatment. In addition, patients are advised to avoid exertion, pay attention to rest and increase nutrition appropriately.
