I don't know if I have anything, but I can be anywhere and there is a nice scent or an unpleasant smell. It is brief, a minute or less. Then it is gone. I attempt to sniff the air thinking that I can discover the source. There is never anything around that would even carry the smell. I do have a very, very good sniffer, but I can be in a forest and smell cookies baking. I wondered if it would be associated with my autoimmune or is it a development with say neuropathy. I have it in my feet and I now have the area just below my knees, a type of neuropathy involving my skin. I've been blessed with a lot of issues and I'm not being hurt by this, I just want to know it others have this.
