Hi. Thanks for your query. Read and understood your history and concerns. You give a history of falling down, loosing balance and feeling of clogging of the right ear with ringing and now that you are feeling better have attended to the duties. You must see a Doctor for clinical evaluation and examination and if needed a CT scan for the brain and the mastoids/ears. I can understand that you are feeling normal but the possibility of an internal injury should be borne in mind and ruled out to be stress free and if there are some positive findings , they can be treated as such.
