hello thanks for consulting at hcm,,
jaw pain could be due to
referred pain from maxillary sinus,,since you have history of
sinusitis and
headaches,,and also due to teeth being symptom free i,e no deep
dental caries, and calculus,,so either ways you need a consult with a oral physician for a check up,,you may need x-rays like iopa radiograph,, paranasal sinus view-- to check for opacification of maxillary sinus,, you take steam inhalation,, it gives relief,, also drink warm water,,also check the vitality of the teeth involved on the pain side,,plz consult a oral physician for the check up and treatmen,,hope it helps..take care
