For a long time, I've had a recurring problem with scent.
Every once in awhile, I get a "smell" inside my nose--it's very similar to burning garbage. Because I think the smell is me (which other people have assured me it is not), I tend to bathe quite frequently and take extraordinary measures to make sure I'm not smelling myself.
This will last about a week, and the last time I had this happen was about 2 1/2 years ago.
If someone could clue me in as to what this could be or where I may find information, let me know.
