3 doctors weighed in: Can post nasal drip result in mucus entering into lungs and accumulating there, or does it just go in stomach ? 3 doctors weighed in Want a second opinion?

Post-nasal drip may become worrisome if it is accompanied by symptoms such as persistent cough, severe stuffy nose, recurrent infections, blood tinged mucus, or voice changes. In severe or persistent cases of post-nasal drip, a patient may be referred to an ear, nose, and throat specialist, explains Dolan.It is more likely to be caused by the mucus becoming too thick or by irritation of your throat.
