I've "always" (I'm 66 Yrs Old) Had A Stuffy Nose.

I've "always" (I'm 66 yrs old) had a stuffy nose. I've been told this is due to a minor deviated septum and chronic sinusitis (CT scan confirmed both back in 2005?) and suffer from bad seasonal allergies. I started using Flonase this last summer. I'm constantly, that is not hyperbole, blowing my nose. As of late, the last month or so, my nasal discharge, at least once or twice a day, contains "large" blood clot material. I've never had a bloody nose. Is this something I should be concerned about? Thanks much, Dick Carter
