Thanks for your question.
You are most likely suffering from upper respiratory Tract
illness. Now this can be in sinuses
or can be in lungs . Ideally you need to get them evaluated. You should get examination by an ENT specialist
and later get X-rays of sinuses and chest (according to what doctor suspect ).
Lastly acid reflux
from throat can cause this also .
This is general guideline. If you want to discuss this further please get back to me.
