How Can Itching In The Ears Be Treated?

i have been having some trouble with my ears. started with itching and after treating with ear drops i had an ear infection that ended with me feelinglike i was underwater. i then had a stroke which i m not sure is unrelated or not. i still had trouble hearing out of my left ear but aft a few weeks it seemed that as my left ear improved my right ear worsened. my primary care saw my right after i was discharged and he said there was build up but its bee six weeks now. the ear nose and throat doc said something about havng something like excema in my ear canals. anyway i ve gone from itching in both ears to excess build up in first the left then right, then now i have these little bumps blister-like just inside my ear, the opening and around the ear and behind the ear? is this some kind of skin issue or infection?
