hello and welcome to hcm forum,
i am glad you wrote in, according to the dental history provided by you, it is not clear what dental treatment have you undergone, but ,yes you have developed infection in the treated area.
i know the pain you are experiencing is severe and radiating,
therefore,kindly visit your dentist
as he/she will prescribe you antibiotics and anti-inflammatory , ketorol won't help.
i recommend warm saline rinses, along with antibacterial(betadine
) mouth wash 3-4 times/day.
i hope i answere your query,
i wish you good health,
