Hi.. Thanks for the query.. I have gone through your query and can understand your concern.. As per the symptoms it looks like there have been either injury or dislocation of the jaw joint that is leading to pain in jaw and ear and pain especially on moving the jaw side to side and opening the mouth wide.. I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigation like Panoramic x ray can help in diagnosis and treatment can be done accordingly.. You can be advised a course of painkiller like Ibuprofen and muscle relaxant like Chlorzoxasone.. Take a soft diet and avoid biting on something very hard.. Avoid excessive mouth opening like while yawning, laughing etc.. Massage the sides of the face with round gentle motion of finger tips.. If jaw joint problems is ruled out then night guards and physiotherapy can be advised... Hope this information helps.. Regards..
