Hi, @jersey47 - wanted to greet you and welcome you to Connect. I'd also like to introduce you to @januaryjane @upartist and @charlottescot. They also may have experience with having clear ear drainage and how to get it to stop.

Since there are many acronyms in medicine in general and in pharmaceuticals, wanted to clarify the substance you were talking about when you said "CSA powder." Is this perhaps auricularum (otic) powder used for external otitis?
