If the fever-reducing medicine is not effective, you can use a fever-reducing injection. For example, if the temperature is below 38.5°C, it is considered low fever. Low fever can be physically cooled by drinking more water and wiping the affected child’s neck with a warm towel, either for adults or children, and rubbing the armpits, groin, inner thighs, etc. You can take a light diet, do not eat spicy and irritating and greasy food, green vegetables, fruits, milk are all allowed to eat.
