@lisalucier– Thank you for inviting me into this discussion. @iceblue: During the beginning of my PTSD journey my first symptoms were migraines. Although they were pretty bad they were also filled with other sensations other than pain. One in particular, phantosmia, was particularity noticeable. That was smelling all sorts of smells. This was preceded by a second cancer and chemo. I agree, it's disconcerting! I never got it checked out. My husband was familiar with it and explained it to me. Now, 12 years later I still get these occasionally. And who knows, maybe there is smoke in the air for real that's been carried toward you. Maybe someone new in your neighborhood or driving by in a car? Who really knows what goes on in our brain and how medicines might influence changes. If this is very bothersome perhaps do some of your own research, like googling your current medicines and the effects of increasing dosages. Do you smell any other odors?
