I went thru this once, I did have infection but not my nasal area. Oddly my daughter had it too. An intern told us, "from your stomach" of course last thing you wanna hear. Well needless to say, we went home ate bread. Helpped our feelings, but it ran it's course. Good luck
Hello and hope you are doing well.
Your symptoms could be due to olfactory hallucinations. Phantosmia most often occurs as a result of a head injury or upper respiratory infection. It can also be caused by temporal lobe seizures, sinusitis, brain tumors, migraine, Parkinson's disease and stroke. You may need proper evaluation by your GP, please consult him for a neurological assessment. He may then refer you to a neurologist if needed.
Hope this helped and do keep us posted.
