So for the last two years my left nose and left ear have been clogged what's some things that can cause such a long congestion. In the mornings I feel fine as the day goes on it get worse. Could I be allergic to pot. I make concrete all day always breathing in the portland I try not to inhale it but can't always avoid it. When I drive to let's say Salt lake the altitude drop can be so extreme that when my ears pop it feels like something was drilling threw my ears.
