Hi , Hope you are doing well. My Mother in law has an issue in left ear,the eardrum isn't there .earlier artificial membrane was in installed but then it became obsolete so had to be removed. And the pus that collects block the nerve to the brain so at times she suffered severe headaches n also unconsciousness at times. Would it be okay for her to travel through flight ? Or it would be an issue for her coz of the pressure . And is there a solution for this situation . I know there are solutions out there and we just need to find them so I request you to please help me with this so that I can help my mother in law . Thank you so much for your help! Stay Safe.
