Had RC on front tooth in April. It still hurt in July(just not as badly as before). Went back to the endo and family dentist. They said that the canal was overfilled and that was what was causing my pain. Dentist remarked that these issues usually "dissipate in 5 years." Do I just live with it??? It isn't too pleasant but it does seem doubtful that I have an infection since I have had oodles of antibiotics and it has not made a difference. Pain is like a "pins and needles."
