Hi,
It looks like
phantosmia or phantom smell. It leads to strange smell through the nose that others cannot experience.
It can occur due to a number of conditions like
nasal infection and polyps, migraines, oral and dental infection, smoking habit, condition related to the nervous system like Parkinson's disease, Alzheimer's disease, stroke,
head injury etc. I suggest you consult a medicine specialist and get evaluated.
Along with that, clinical evaluation investigations like nasal
endoscopy, MRI, CT Scan etc as per the suspected cause can help in the diagnosis and treatment and can be planned accordingly.
As of now you can do saline
nasal irrigation, steam inhalation with few drops of eucalyptus oil in water, chew flavored sugar free chewing gum and limit intake of high aroma foods like onion and garlic.
Hope I have answered your query. Please let me know if I can assist you further.
Regards,
Dr. Honey Arora, Dentist
