Welcome to HealthcareMagic. A more or less constant running nose or feeling of nose blocked with occasional phlegm while having no cough
and chest intact are generally symptoms of upper respiratory tract
. You must be having something called as Hay fever
, or something else of allergic grounds.It generally flares in particular seasons. YOu may correlate with your background history. Anyways , for all these you may go to a ENT specialist
or else allergologist or even a chest physician or a general physician can guide you. Take care.
