What Does A Phantom Pepper Odor Indicate?
Several possibilities as follows...
Detailed Answer:
I read your question carefully and I understand your concern.
There can be several possible causes to that smell dysfunction. The most common possibility is an upper respiratory tract infection like a sinusitis or rhinitis. Nasal polyps are also an upper respiratory tract issue possibly related. So an examination of the nasal cavity would be the initial step.
If nothing is found a neurological cause should be considered. It may be an early symptom of Parkinson disease, so an examination for other Parkinson signs is advised. If there was any head trauma that would be a possible cause as well.
If you have been taking antibiotics (for a long period) or have been exposed to any toxic solvent that would also be a potential cause. Long term heavy smoking is also a possibility (though usually would lead to loss of smell).
I remain at your disposal for other questions.
