<s>[INST] I have had pretty severe jaw pain for over a week.  I've been to dentist- all is fine with my teeth. though there are signs of grinding.  Been to fam prac Dr.  He said it's prob TMJ- been to massage therapist- that seemed to help for a day--been to chiropractor twice--had back, neck and jaw adjusted.  Didn't seem to help.  Now, I'm feeling nauseous.  I'm dizzy and my jaw hurts. [/INST] Hi dear ,Welcome to HCM,Understanding your concern .As per your query you have jaw pain after recent root canal therapy . The symptoms you mention in quoery 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 complivated . I would suggest you to consult dentist again for proper examination . Doctor may order x-ray torule out causes like bruxism , 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,Dr. Harry Maheshwari </s>
