Question: I keep smelling a sweet perfumey odor that no one else can smell. It has been happening for about a week now. I have not changed any soaps or deoderants. It is driving me crazy. Do you have any idea what I could be experiencing? Sue

Answer: Dear Sue,

Smell disorders include the following:

- Loss of sense of smell
- Sense of smell is reduced
- Odors become distorted
- Perceive smells that are not present

Illness, injury, respiratory infections, sinus infections, dental problems, hormonal disturbances can all be causes of smell disorders.

Smell disorders are diagnosed by a doctor by performing several tests.
