Thanks for your query, I have gone through your query. The pain in the jaw could be because of the wisdom tooth. usually the pain from the wosdom tooth cannot be localised and it radiates to the other sites in the jaw like cheek, temporal region and head. Consult a oral physician and get the radiograph of the wisdom tooth done and get it removed. you can take a course of antibiotics and analgesics like amoxicillin 500mg and metronidazole 400mg tid for 5 days (if you are not allergic). I hope my answer will help you, take care.
