For fever and headache caused by mastitis, symptoms can be relieved by physical cooling, medication, expressing breast milk and anti-infection treatment. 1. Physical cooling: If the temperature is below 38 degrees, you can use warm water or alcohol to wipe your body and put on antipyretic patches to lower the temperature. 2. Medication: If the temperature has reached 38 degrees or more, you need to take oral cooling medication, such as ibuprofen suspension. 3. Expression of milk: Mastitis is usually associated with milk stagnation, hard lumps in the breasts and fever, and it is necessary to express the milk stagnation in the breasts until the whole breast becomes soft, so as to avoid the formation of mammary gland abscesses. 4. Anti-infection treatment: if necessary, follow the doctor’s instructions with oral antibiotics for anti-infection treatment, commonly used antibiotics are cefixime, amoxicillin granules and so on. 5. Surgery: If the mastitis forms a localized abscess, it is necessary to perform incision and drainage of the localized abscess. It is recommended that mastitis sufferers seek medical attention in a timely manner, and strictly follow the doctor’s instructions to carry out the appropriate treatment, not indiscriminate use of medication.
