What that was in my experience learned was, was basically using an ear flusher after putting in the ear drops and waiting for about 5, 10 minutes, is a good thing. Who'd a thunk, right? ;-D. It now feels like my ear is clean. First time in years. This, again just me, was much more effective than the ole shower head rinse. The only thing is the ringing, but I've learned how to deal with that. So it's all good.
