Root canal complications

Had a root canal late May. I'm still having pain that requires 800 mg ibuprofen to stop. It was #30 I believe. Pain often starts at the hinge of my right jaw. Also can feel it in the area of that tooth. I assume the root canal failed?

It sounds like its not working.  It may be failing.  Has it improved at all over the last few weeks?

I this your rot canal doesn't work out and if have problem than fastly rushed to dentist  otherwise you will have much more problem and there is a chance of infection so it's better to take cure and proper medication.
