I have had severe migraines for several months. They will disappear and then come back out of the no where, mostly in the front of my face and forehead and will last for days. Sometimes keeping me in bed. Several times I have also seen smoke in the air like there is fire somewhere and the latest, started about a week ago, the smell of burning rubber, I cam be in the car or at home, does not matter where. I still smell it. Should I be concerned?
