Post Nasal Drip and Runny Nose
When you are experiencing a sinus infection, you might require blowing your nose sometimes because of the nasal discharge, and might lead to green, cloudy or yellow. Such discharge comes from drains into the nasal passages and your infected sinuses. The discharge might also drain back into your throat and bypass your nose. You might feel an itch, tickle, or even a sore throat. This is known as postnasal drip, and it might lead you to cough at night when you are lying down in the morning after waking up and at night before going to bed. It might also sound hoarse.
