I am a inflammatory breast cancer survivor, a few months ago I had a few severe dizzy spells, and have had prolonged sinus issue..left maxillary , cheek are is numb and feels clogged. Nasal membranes have been inflamed...just finished a five day steroid regime along with an antibiotic and allergy meds. Still feel the numbness, no drainage or other symptoms....worried about mets from my IBC cancer to nasal area....should I be concerned. I think it has been about 3 mos since first sinus issue
