If you develop a fever with a temperature of 39°C or higher during breastfeeding, drink plenty of plain water to prevent dehydration caused by high fever. Wipe the forehead, armpits, groin and other areas with warm water and take oral ibuprofen suspension. If the fever does not subside and is accompanied by coughing symptoms, it is recommended to visit a respiratory medicine clinic, where anti-viral drugs, antibiotics and coughing and phlegm-relieving drugs are usually given for symptomatic treatment. In Chinese medicine, fever caused by wind-cold cold is usually treated with Jing Fang Shen Poison San plus reduction. For fever caused by wind-heat cold, add or subtract Yin Qiao San. If the fever is caused by mastitis, Western medicine generally uses antibiotics for symptomatic treatment, while Chinese medicine generally treats symptomatically with drugs to clear heat and detoxify and dissipate swelling and nodules, suggesting a combination of Chinese and Western medicine.
