Thank you for your prompt reply Sue. I do a nasal rinse nightly followed by Flonase as I have sinusitis. I did read yesterday that in lieu of spraying my Flonase straight up into my nostrils to insert/spray at an angle. I did this approach last night and that seemed to help as not hearing the fluid this morning. Appreciate your advice and will check with my doc should the fluid sound returns. Thanks for the tip re: Valsalva maneuver.
