Hi Dear , As per your query you have ear ache since you met with an accident . Well there can be many reasons for ear ache like ear infection , wax builup , eczema of ear canal , impacted tooth , trigeminal neuralgia and temporomandibular joint ( TMJ) . In your case it seems to me that the probable reason for pain is either TMJ problem due to accident or impacted tooth . I would suggest you to consult oral surgeon for proper examination . Doctor may order tests like CT scan or MRI to confirm the diagnosis . Doctor may also check the bite plane . Doctor may surgically remove the TMJ deformity if there is any or prescribed muscle relaxant along with anti inflammatory or extract the impacted tooth depending upon the diagnosis . For now eat soft food , avoid wide opening of mouth and take ibuprofen or acetaminophen for pain . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
