Hi I am Dr Ravinder Sharma. On the basis of information provided it appears that you have a problem of upper or lower respiratory tract
. In the upper respiratory tract it may be from the sinuses
More likely it appears to be from chest. It may be because of a infection or a neoplastic affliction of chest.
I advise you for a ENT consultation and Chest consultation and some tests like sinus xray and X ray
chest PA view and sputum smear examination and culture sensitivity to resolve the issue
I hope this answers your concerns. Feel free to contact me if you want further information about it
