"Does someone in your life have trouble breathing as a result of chronic sinusitis?

You'd be surprised how common this is. Experts say between 16 and 18 percent of adults have chronic sinusitis -- now officially known as rhinosinusitis -- that makes them unable to breathe through their noses. The condition, which leads to repeated sinus infections, causes frequent coughing, sneezing, and headaches, and can lead to weakness and fatigue. Some head and neck experts say that chronic sinusitis can actually cause people to suffer more long-term problems than COPD."
