About three years ago I was sitting with the family watching tely when I could smell a chemical odour that smelled like electrical wires burning. I said to my family that I thought the tely was on it's way out. Of course nobody else could smell any-thing. My neurologist asked me if it was followed by a head ache saying that it was a fairly common thing to happen before a migraine. As this was n ot the case he sent me for tests for epilepsy which also proved negative. It kept up ,on and of, for about a year or so then stopped. In hindsight it was during a period of extreme stress and so I just put it down to that. Regards Mary Thompson from Oz.
