The bumps are arised due to abscess developed at the site of impacted wisdom tooth
which is inflamed.
Throat pain and ear infection
,fever and headache are the symptoms usually associated with impacted wisdom teeth.
Please do visit an oral and maxillofacial surgeon and get clinical as well as radiological evaluation done.
Depending on the space available for tooth eruption
,it has to be either extracted or flap overlying tooth has to be removed.
Maintain oral hygiene
Hope this helps.
