an allergic reaction to neomycin is actually quite common. i see this on occasion with neomycin-containing eardrops. your doctor needs to prescribe something else for you as well as treat the allergic response. one more consideration since you have had this problem for a month is that the cause may not be bacterial. you could easily have a fungal infection in your ear canal requiring an entirely different treatment.
