Hi, Off and on for several years I have had an acrid odor that I feel is emminating from the cells in my nasal area inside my nose. It is not the sweet odor I hear others talk about but more of an unpleasant acidy type odor. Actually, it is not like anything I have ever smelled elsewhere. I asked my husband if he can smell it but he says no. On the other hand, his sense of smell is not too great. I can't seem to smell it on my hands or anywhere else as it all seems concentrated in the cells of my nose. I am a Type 2 Diabetic and am worried I may be having some kind of ketone problem but I haven't ever heard anyone describe it this way. It is an unpleasant odor and it distresses me as I don't like the smell plus I worry that others might smell it. I would like to mention too, that I occasionally have "auras" that last around 30 minutes but I don't get a headache after these auras. These auras are like heat coming off hot pavement and some zaggidy lightning-like light in my eyes. It always happens in both eyes at the same time. Thanks, Kim.
