Thank you......I am using Swim-ear for a stopped up feeling in my right ear, mostly....I just started to use it and my doctor said it is alright...It says, on the box that is the original swim-ear......NO WHERE ON THE BOX OR BOTTLE, DOES IT SAY, HOW OFTEN TO USE... IT JUST GIVES DIRECTION TO: APPLY 4-5 DROPS IN EAH AFFECTED EAR......COULD YOU PLEASE TELL ME, IF YOU KNOW, HOW OFTEN DO I DO THIS.... My stopped up ear sensation, started with an allergy about a year ago, and I have been seeing Dr. J. Lester, O.D for one year and we have tried many allergy meds.......I am allergic to Papas grass, which started this.....I have gone on line, and view many folks who have their Eustatian (sp?) tube blocked from allergies... . Help...Help....Doctor...... Barbara J
