hi i have an ear infection at present, initially i had one in december which was tx with oral antibotics, and then last week got the same symptoms of a pressure feeling, small amount of smelling discharge, dull feeling - no pain though as such - this time im treating it with Otosporin drops, this is my 6 day applying them, and i am still having periods of the day where ear is feels blocked, especially after each application of the drops or after eating - is this normal??
