I Am On Neomyosin Polymyxin B Sulfate And Hydrocortisone Suspension

I am on Neomyosin polymyxin B sulfate and hydrocortisone suspension I have chronic otitis media but also have a PE tube in my left ear it is not uncommon for me to get frequent ear infections this is the first time I have use this med , it does sting- severely for several minutes but then continues to ache. I did have drainage noted a few hours after using the drops. And my ear canal itches. I normally use another type of anabiotic it also causes stinging but doesn't last as long.
