To effectively treat fever caused by pediatric tonsillitis, you can choose symptomatic anti-inflammatory medications, regional treatments such as laser therapy or medication irrigation, and painkillers if the child’s throat is particularly sore. If the fever persists, it is crucial to seek medical attention promptly. Tonsillitis often recurs, so if there are similar symptoms, surgery can be considered after the inflammation is controlled. Parents should also ensure their child stays warm to prevent catching a cold and triggering a recurrence of tonsillitis.
