dear user i would like to tell you that these symptoms refer to bacterial infection of ear secondery to trauma you had ...........this infection cause effusion of fluid and discharge that makes you feel these symptoms.............the effect of infection should be taken seriously as in some cases this may cause severe pain and itching and popping and also temporary hear loss or damage of ear and permenant hear loss as complication.........so treatment should begin as early as possible to avoid these effects...........the treatment mainly with antibiotics such as erythromycin as it is very useful in ear infections management........ ..you should consult ent specialist for examination of ear and doing blood culture as investigation and also do drainage of fluid and discharge..... wish you healthy life
