Thanks for writing in.
I would suggest you get your nasal cavity
examined by an ENT surgeon. First a deviated nasal septum
needs to be looked fir. Apart from this, if you are having any suspicious problem with maxillary sinuses, a CT Scan
of paranasal sinuses
coronal plane may be necessary. This will throw light on osteomeatal compkex (place where sinuses open into nasal cavity).
Hope this helps.
