I have the same problem with my sense of smell. Since 3/06 (my brain surgery), I have been horrible. Paint fumes, chemicals, and smoke really gets me. You would think that I'm acting, I'm so dramatic! I feel as though I can't breathe, it's so bad.
Strangely, I've lost smell of things that smell good. It makes no sense to me. I haven't ever told a doctor about it, and asked why, because I presume he'd think that I'm full of it! LOL
If you have that same trait, of losing the sense of good smells, then there must be something to it, and it's worth asking a doctor
Let me know!
