So, about 3 weeks ago I had a pretty bad cold. All my symptoms cleared up EXCEPT my nasal congestion. I know I don't have a sinus infection as I went to urgent care about a week ago for it. Also no tenderness when I press on the sinuses. I've been taking 12 hr Pseudoephedrine twice daily, which helps for a few hours, but then seems to wear off. The congestion seems to switch nostrils randomly, though it is also frequents both. When I blow my nose it is normally clear, except in the morning when it's slightly brown/yellowish. I do have a deviated septum, but I've never had this problem in the past. I also take OTC Zytrec daily to try to help. I'm 19 years old. I was wondering if there were any other possibilities besides sinus infection, nasal polyps or my deviated septum.I've got a trip coming up soon and I'd like to be able to enjoy it. Thanks in advance for your help!
