9Bad Breath
As said above, the infection that causes sinusitis can affect your postnasal drip, including your throat and lungs. As a result, bad breath could happen when the bacteria attack these areas. This condition might occur persistently and make it hard to communicate with other people. Also, sinusitis can trigger sore throats, which might result in bad odor in your mouth as well. The only way to alleviate the condition is to treat the underlying infection. [9]
