I have had pretty severe jaw pain for over a week.  Ive been to dentist- all is fine with my teeth. though there are signs of grinding.  Been to fam prac Dr.  He said its prob TMJ- been to massage therapist- that seemed to help for a day--been to chiropractor twice--had back, neck and jaw adjusted.  Didnt seem to help.  Now, Im feeling nauseous.  Im dizzy and my jaw hurts.
Hi dear, Welcome to Chat Doctor, Understanding your concern. As per your query you have jaw pain after recent root canal therapy. The symptoms you mention in query are probably occur due to high point that remain after treatment. Due to high point your temporomandibular joint (TMJ) causing problem and because of arthritis things got further complicated. I would suggest you to consult dentist again for proper examination. Doctor may order x-ray to rule out causes like bruise, dental infection and other TMJ problems. Doctor may relieve the high point, give night guard and may prescribe further antibiotic course. For now try to eat soft or take liquid diet and do not open you mouth wide. Doctor may also refer you to gastroenterologist for nausea. Hope your concern has been resolved. Get Well Soon. Best Wishes,
