Welcome to health care magic forum.
Thanks for sharing your concern.Tonsillitis
as well as ear infection
has to be treated either with antibiotics or tonsillectomy
depending on severity of inflammation.
If symptoms persists,get your wisdom tooth checked for any inflammation associated with the same impacted tooth.
Tooth has to be either extracted or saved depending on the position of tooth as well as severity of inflammation.
Meanwhile,gargle frequently with lukewarm saline.
Maintain your ears dry.
Hope this helps.
