The problem you are describing can be associated with the allergy
and with the sinus. If you are having some sort of sinusitis which is related with the nose sinuses
infection or allery, this can present as the problem which you are facing with. Allergic sinusitis
is a chronic prolem and is mostly because of some allergic substance and this can lead to a chronic condition.
I would suggest you to consult some ENT surgeon regarding this problem and afte proper history and examination and if required some investigation, it can be confirmed whether this is some sort of allergic problem or some thing different.
