Pharmacy closed been on Flonase nasal spray 2days havin odd feeling an pressure along sides of nose an down into my front teeth, is this a side effect?

Sinus pressure? Roots of the upper molars often protrude up into the maxillary sinus. Flonase is a nasal steroid (anti-inflammatory) that is used to shrink membranes of the nose and open the ducts that drain the sinuses (that open on the top--so you must "stand on your head to drain them!) pressure means: still inflamed. Try using neilmed with a double salt mix-hypertonic solution. No med side effects.
No. Probably due to swollen sinuses, swollen mucous membrane, or possibly tooth infections. See your Dentist for evaluation.
