Usually OK: If you are on amoxicillin , infection is unlikely. However root canal is a traumatic procedure and may cause pain and swelling for a few days. You are doing the right thing. But if you can't get a pain medication, try placing an ice pack at the area for up 20 minutes at a time. Your PCP may also be able to Rx a pain med for you if it is intolerable. Call dentist if problem worsens or persists.
