I am very concerned about my wife.

[apostlejw]

Every now and then my wife smells a very disturbing odor. She can't tell where it's coming from, but it makes her feel very sick. She smells it no matter where she is, it just happens. This takes place about 2 to 5 times a week. Sometimes more, sometimes less. Can anyone help us?

[I-SING-FOR-HIM]

I HAD THAT ONCE AND IT WAS A SERIOUS SINUS INFECTION...CHECK IT OUT.

Ditto as above! SINUS infections can smell terrible! fotunatly others around you do not smell it though, although I had my wife smell up by my nose as i breathed out slowly and she could smell the sickening smell.

the other thing this might be a migraine aura, since she feels ill afterward...check out migraines on the web  good luck
