[|AI|]  Thanks for using Chat Doctor. Read your query. I can understand your predicament. The pain is due to the reinfection of the root canal tooth. I would advise you to:*Continue with the medication and visit your dentist as soon as possible.* Get a radiograph done and proceed with the removal of crown.* Get the appropriate pretreatment done.*Do warm saline gargling. Hope this was useful. Thanks and regards.
