Hi I am concerned because I intermittently smell smoke, the smell is similar to the scent of a cigarette being lit. Sometimes I feel it takes my breath away because it is so strong. There is never anyone smoking or smoke from any other source when I smell it. One evening last week I had double vision, it was very brief, maybe for 5 min and it followed a dizzy episode. I have hx of migraines, my most recent one was about 1 1/2 months ago and I was given Toradol IM. I have not felt right since that last migraine. Just wondering if you have any thoughts on what might be causing that smell.
