10 Sinus Infection Symptoms
Reviewed: Dr. Mera
Symptom #7: Cough
A productive cough is another symptom that commonly accompanies sinus infections. Often, sinus infections are mistakenly diagnosed as bronchitis or a common cold. However, a cough that is caused by a sinus infection tends to get worse during the night and especially in the morning when waking up, while in cases of a common cold or bronchitis a person tends to cough consistently during the day and during the night.
The reason the cough occurs mostly during the night and in the morning is because the sinus drains down the back of the throat when in a lying position, which will trigger a cough. A persistent cough during the night because of post nasal drip will lead to sleeping problems as well.
