Otomize spray

Hi, have had ear infection for a while now.. they gave this otomize spray it was stinging for first few days as i was told it would because my ears are inflammed okay so i carried on using it and using it for a week made my ear pain slightly better but again this week everytime i put it in it hurts and i get like a burning sensation. Have been told to put this in my ears before ent can see the under lying issues..this morning i had yellow discharge coming out of my ears please help.
