Historically I've had a frequent colds that turned into sinus infections..and it seems like my nose is at least a little stuffy.
Just to add my 2 cents. My ENT recently checked my sinuses (including CT Sinus) and at the time they were clear/normal. ) What's strange is he still asked if I wanted to do the sinus surgery where they clear out the tissues seperating the sinuses and make one big sinus..
