hello and welcome,
As per the details you have produced,
you are suffering from the symptoms associated with impacted wisdom teeth which is erupting.
warm saline gargle may give relief.
in mouth .vomitting are the symptoms .
I would suggest you to visit an oral surgeon soon .
Clinical and radiological examination will reveal the condition of teeth.
Extraction or flap overlying teeth has to be removed to enhance teeth eruption.
meanwhile maintain good oral hygiene
