Post extraction of wisdom tooth usually shows the symptoms as you mentioned,if dry socket
has developed at the site of extraction.
I would advice you to take rest for another 5-6 days.
Avoid anxiety and stress.
Gargle frequently with warm saline or betadine
Maintain oral hygiene
Take complete course of antibiotics-analgesics prescribed.
Clean the socket with gauze soaked in povidine iodine solution.
If symptoms persists,please do visit a dentist
Hope this helps.
