Earaches can range from mildly unpleasant to very severe. They generally start between the third and ninth day following surgery. Earaches can linger anywhere from three to eight days. To make your kid as comfortable as possible, several types of pain management are employed. Acetaminophen (such as Tylenol) and ibuprofen (such as Advil or Motrin) can help reduce fever and pain associated with ear infections. Warm compresses applied to the neck can also soothe a sore throat and relieve pain caused by an inflamed membrane surrounding the ear canal.
