Hello, I can relate to alot of what you are saying. I started developing sinus trouble in my teen years.My sinus problems sound alot like yours. I get repeated infection throughtout the year. Now, when I get a sinus infection I have to take a 6 week course of antibotics just to get rid of the infection.
I have a few suggestions for you. 1 is sinus rinses they really work. They take a little time getting used to doing. Get a flu shot when the time comes around. Get plenty of Vitamin C.
Saline nose sprays are good. Also talk to your doctor about
taking a prescript
ion nasal spray. Like Nasonex,Flonaase. I take Nasonex nasal spray .. Best nose spray I have ever used. Really helpful if you have nasal congestion with or without sinus infection. It isnt over the counter. need a doctors order for it. Hope this is some help. Good luck. Welcome.
