must always be considered a warning sign for neurological (nervous system) problems and must be taken seriously. Having an "aura
", with strange smells or the feeling you are getting of a weird taste in your mouth can also be concerning for neurological problems, as can the vision
change. I would advise that you be medically evaluated for these symptoms. When you see a physician, it will be important to tell your entire health history, any family history of medical problems, and any other recent symptoms that you notice.
