Went And Saw My ENT Doctor Last Week. Have Had

Went and saw my ENT doctor last week. Have had a clogged inner ear now for a year and his only advice was to put another tube in or take steroids. He already knows I can't take oral steroids because I'm diabetic and it jacked my sugar level up from 110 to over 240 with a single dose. When I asked him do they make a steroid ear drop right to the problem area instead of taking one that affect my whole body he said NO. Is that correct or do I need a different doctor?
