Hi Cedar,
Often when I have an aura sz. (simple partial sz.) I will smell a very odd smell like natural gas, deviled eggs, or a burnt odor. My epi told me this was all part of an aura sz. The foul smells only last a few seconds and they are gone. Could this be what's going on? Check out the following websites for more info.
