Thanks for writing to us.
The symptoms are associated with impacted wisdom tooth
which is inflamed.
Please do visit a dentist
and get a thorough clinical as well as radiological evaluation done.
Depending on the position of impacted tooth
,it has to be either extracted or flap overlying tooth has to be incised and removed.
Take complete course of antibiotics-analgesics.
Gargle frequently using warm saline or betadine.
Liquid discharge is due to the formation of abscess at the site of impacted tooth.Ear infection
will subside once the treatment has undergone.
Hope this helps.
