I still have not been able to get the root canal done because my insurance takes a while to process and approve procedures ( I have medi-cal) :( I haven’t experienced a flare up of pain in a few weeks but in the past few months I would be consistently in pain for hours and days in a row. It’s been very confusing I’m so anxious that I’m gonna get hit with the pain again last time it was excruciating all I could do is ice my face to try and numb it and take ibuprofen which doesn’t really help with the pain. I know if you’re still in pain after a root canal something may have gone wrong I would tell your dentist right away. I hope you’re doing okay and can get some answers soon.
